CHAPTER SEVEN — THE OTHER INVITATION

At four thirty, Ethan received an email from Blue Current congratulating him on hosting the official launch of the company’s autonomous underwater inspection system.
The message included an itinerary for visiting investors.
His name appeared beneath the title Community Technical Advisor.
Ethan had never agreed to that title.
A promotional image showed an orange robot moving through clear blue water.
The caption described the machine as an original proprietary development by Oliver Venn.
Priya stood beside him when he opened the attachment.
“That’s our front guard,” she said.
“It’s not your whole robot,” Ethan replied.


“Look at the base.”
He zoomed in.
A diagonal brace inside the housing matched a repair Mateo had made during the spring.
Priya seemed more hurt than excited to find another similarity.
“He watched us work,” she said.
“He told us our ideas mattered.”
Ethan forwarded the invitation to Ms. Rios.
She called within minutes.
“Don’t cancel the visit,” she said.
“You want them to come?”
“I want the people who are about to give him money to hear from the actual builders before they make their decision.”
“Are the kids ready for that?”
“That’s what we have to ask them.

”
The parents and students met around Ethan’s dining table.
Outside, the pool service had begun skimming the thick material off the surface.
Ethan had explained the contamination honestly and agreed to pay the emergency cleaning charge himself until Carol could reimburse him.
The technician promised that draining the pool would be considered only after checking the water quality and equipment safely.
Nobody would enter the pool while it remained contaminated.
That practical decision frustrated Carol, who kept glancing at the deep end as if a submerged piece might disappear at any moment.
Ms. Rios drew two columns on a sheet of paper.


One was labeled DEMONSTRATION.
The other was labeled INVESTIGATION.
“These are not the same thing,” she told the students.
“A demonstration lets you explain how you built something.”
“An investigation decides whether somebody behaved dishonestly.”
“We are not asking any child to conduct an investigation.”
Nell raised her hand as though they were in school.
“Can we demonstrate our own machines without using Oliver’s equipment?”
“Yes,” Ms. Rios said.
“But we may need a different location.”
“The community center has a shallow training tank,” Mateo offered.
“It’s booked for swim lessons,” his mother replied.
“Maybe the college lab,” Priya suggested.


Ethan thought of the large clear water trough used in his old classroom demonstrations.
It was six feet long, three feet wide, and shallow enough for everyone to see inside.
He had stored it at the school when he changed jobs.
“The science room has a test tank,” he said.
“If the principal approves, we can set it up in the gym.”
Sam frowned.
“That’s smaller than a pool.”
“Then build a course that fits it,” Ethan replied.
The teenagers began talking over one another.
They drew a narrow obstacle route on a napkin and debated whether a robot could retrieve an object without touching the walls.


Ethan watched their faces change.
They were no longer discussing what Oliver might take from them.
They were deciding what they could make together.
Ms. Rios called the principal.
The answer was provisional but encouraging.
If parents supervised and the equipment was safe, they could use the gym for an educational showcase.
There would be no official scholarship award because no independent judging panel had been arranged.
That disappointed the teenagers, but they agreed that showing their work mattered more than accepting a compromised prize.
Carol sat at the end of the table, listening without speaking.
Nell approached her during a break.


“Did you really dump compost into the pool?”
Carol nodded.
“I thought I was helping.”
“You could have made me look guilty.”
“I know.”
“What if Oliver had claimed I asked you to do it?”
Carol’s eyes filled.
“I didn’t think that far.”
“You have to,” Nell said.
“You always tell me to think two steps ahead.”
Carol gave a miserable laugh.
“I suppose I deserve to hear that.”
Nell looked toward the patio.
“Why are you so afraid of him?”
“I’m afraid of what he can do when adults are too busy arguing to listen to children.”
“That doesn’t answer my question.

”
Carol took her granddaughter’s hand.
“When I worked at the plastics factory, management used to take improvements from the people on the floor and put the supervisor’s name on the reports.”
“Did that happen to you?”
“More than once.”
“Did you say anything?”
“Not enough.”
Nell withdrew her hand gently.
“Then say something now,” she replied.
Carol looked at her for a long time.
“I will.”

CHAPTER EIGHT — THE INVESTORS

The investors arrived shortly after five in a dark blue rental car.
They were not the intimidating corporate raiders Ethan had imagined.
One was a former harbor engineer named Valerie Shaw,

who wore practical shoes and carried a tablet.
The other was a soft-spoken manufacturer named Colin Mercer, who asked immediately whether they could see the pool.
Oliver met them at the door before Ethan reached the hallway.
“We have had a minor contamination problem,” Oliver announced.
“Our host’s neighbor had an unfortunate episode.”
Carol stood near the kitchen and heard him.
She stepped forward.
“I dumped the material,” she said.
Valerie looked surprised.
“Why would you do that?”
“Because I wanted Ethan to have the pool drained.”
“Why?”
Carol opened her mouth, but Ethan raised a hand.
“There’s a broken prototype component under the drain grate,

” he said.
“We discovered it three days ago.”
“Whose prototype?” Colin asked.
“That’s one of the questions we need answered.”
Oliver cut in.
“We’re experiencing a misunderstanding with student participants.”
“Then let the participants explain,” Valerie replied.
Ms. Rios brought Priya, Mateo, Nell, and Sam into the living room.
The adults took chairs, while the students stood behind the coffee table with their notebooks and prototypes.
Priya began by showing the development of her team’s steering guard.
She explained what problem each version had solved and why they rejected several more complicated shapes.
Mateo described the cracked mount and the pencil mark beneath his silver tape.


Sam demonstrated a tiny camera platform that used ballast instead of propellers to change depth.
Nell explained how the orange machine had ignored her controller Thursday evening and broken its guard at the bottom of the pool.
Valerie listened without interruption.
When they finished, she asked a question that made Oliver shift in his chair.
“How much of your autonomous system uses student-developed components?”
“Our platform has been in development for two years,” Oliver replied.
“That’s not what I asked.”
“We incorporated some educational feedback.”
“Did you license those contributions?”
“Our participation agreement covers derivative work.”
Valerie read the version the parents had signed.


She scrolled through it carefully.
“It covers evaluation, demonstration, and publicity,” she said.
“I don’t see an assignment of intellectual property.”
Oliver produced the updated statement he had sent Ethan.
Valerie compared the dates.
“This was sent today.”
“It’s a clarification.”
“It is a significant change,” she replied.
Colin turned toward the students.
“Did you know the company intended to manufacture a machine based on these parts?”
Priya shook her head.
“We thought he was evaluating us for a contest.”
Mateo crossed his arms.
“He told us to focus on learning, not ownership.”
Colin looked at Oliver.
“You said your team developed the platform independently.

”
“Our engineers integrated the final system,” Oliver said.
“Integration matters.”
“It does,” Valerie replied.
“So does telling people where the parts came from.”
Oliver stood.
“We can discuss licensing after the demo.”
“We can discuss it before any more money changes hands,” Valerie answered.
Her voice never rose.
Oliver seemed to find that more frightening than anger.
He looked toward Ethan.
“You have turned a youth competition into a business dispute.”
“I didn’t write the new ownership agreement,” Ethan replied.
“And I didn’t ask Nell to keep a secret.”
Oliver looked at the teenager.
“I asked her not to interfere with confidential testing.”
Nell met his eyes.
“You told me I could lose my future if I talked.”
The room became quiet.
Carol stepped beside Nell.
“That was the reason I came here today.”
She described the bucket, the compost, and her hope that draining the water would force the missing component into view.
“It was a foolish and destructive thing to do,” she said.
“I owe Ethan the cleaning costs.”
“You do,” Ethan replied.
Carol nodded.
“But I will not let my granddaughter carry the blame for my decision.”
Oliver said nothing.
Valerie turned off her tablet.
“I am not investing in this project tonight,” she said.
Colin nodded in agreement.
“Neither am I.”
Oliver’s face went pale.
“You’re walking away because of a plastic guard?”
“I’m postponing a decision because I can’t tell who you have been honest with,” Valerie replied.
Oliver left the living room without another word.
They heard him climb the stairs.
A bedroom door slammed above them.
Ethan expected relief to settle over the room.
Instead, everyone seemed uneasy.
The investors had not awarded anything to the children.
Oliver still controlled his company and his equipment.
The broken part was still underwater.
Saturday’s event was still uncertain.
The truth had become clearer, but no one could pretend the problem had ended.
