No need to reinvent the wheel, explore your powers with Yu

You consider the idea, but, nah. You ought to let the lovebirds be. Sully for sure has some moves he wants to put on his girlfriend tonight, and bros don't overshadow bros on grad night just because they suddenly gained ultimate power.

The logical choice for a Guinea pig stands right in front of you. Yu's the most excited to help you with this, you may as well take advantage of her enthusiasm.

After observing your other friends for a second, you turn back to Yu, mind made up. "Yeah, let's figure this out. I definitely could use your help till I got a better handle on what's going on. So... how do you feel about being my test subject? It's not too much to ask you to volunteer, is it?"

"Given what we've seen is possible, I should probably be nervous, but I'm up for the job if that's what you need," she says, hesitantly. "You claimed my help, so... it's only fair. Like you said, if you need it, it's yours."

Yu's consent obtained, you think about how best to continue exploring your powers together.
