"Hey, what did I even do? Why are you arresting me?"
"Sorry, but we need you to come in for questioning."
Misunderstanding cleared up?
"Well, it's all right now, kid. It was all a misunderstanding. I've come to take you home."
"Uh... who are you?"
"He's your principal. You can go now. We've repaired the broken window. Sorry for all the trouble we caused you."

"Sis, what was it like when you first awakened?"
"Me? Hmm, I guess it happened pretty naturally. At first, I was a bit out of it because of the amnesia. Then I slept, woke up, and I was fine. My powers awakened, too."
"Ohhh, that's so cool!"
