Trini getting so excited whenever Billy talks about something he likes and inputing questions, genuinely curious to learn more. Sometimes, when he doesn’t tell her what a certain device does, she just decides to toy with it and see if she can figure it out herself. (She rarely does before Billy is yelling at her to not touch a certain button or move a certain wire)
It stresses Billy out sometimes, but it makes working on his inventions so much more fun, especially on the days when Trini is there when he starts a new project and inputs her own ideas.
“Wait, so what does this button do?”
“Oh, gOD TRINI DON’T TOUCH IT!”
“What? Why not? Billy, c'mon just tell me what it does!”
“Trini if you touch that button, the whole place is gonna go boom. Tri- nO STEP AWAY TRINI!”
“The whole place?”
“The whole place.”
That just sums up how Trini and Billy ended up with grass stains all over themselves and Candace Cranston running out into the backyard in nothing but a robe, staring blankly at the 10 foot diameter circle Billy’s latest invention had put in her ground.
Also he starts to teach her breadboarding and code, but finds out Trini knows almost eight coding languages fluently. She’s never seen any of the codes he’s written for his inventions, so she’s left in awe trying to figure what they do. She knows breadboards like they’re the back of her hand, so one day he leaves one hooked up to his computer with a code waiting to be run.
Trini gets super excited because she’s never seen the coding behind all of Billy’s amazing work and decided to run it. What she doesn’t know is that Billy has over a dozen of Breadboards laying around, and when she runs the code, more than half of them start letting out this whistling sound. She stops running the code, which doesn’t work because Billy did something that only allows the circuits to stop running if they’re disabled manually.
Trini’s left bewildered trying to figure out which ones are going off and which ones aren’t, disabling them herself as fast as she can. Billy thinks it’s hilarious (he apologizes of course) and then let’s Trini play around with all of his different coding programs as he finishes up one of his prototypes.
