that's perfect! if he tried to sleep with her early on, she was probably underage and would've been like, uhhh no?? but at 18 she was feeling restricted by nick and started trying to see how much she could get away with, so i feel like she would've been really flirty just knowing that he was a bit older and not really the wholesome tween star type. but whether or not they ever actually hooked up is up to you!
