I meant, Sophia talked about bullying with the principal, trying to punish Aiden, and now Sophia herself is sending him sexy pictures. Imagine if Aiden goes with the pictures to the principal, with Sophia's phone number .... This would be really bad for her.I said in this forum before when people suggested Sophia could get in trouble at school over things happening at the tutoring job. That the principal would most likely just use it to blackmail Sophia, after all, remember the hug he gave Sophia when they first met, he was clearly seeing how far he could push things.
So Principal blackmailing would be the big damage you referring to, so maybe you're on the right path but I just don't see Aiden working with the principal, Aiden tasks might involve the Principal or another teacher via them catching Sophia but I don't think it lead to anything overly bad for Sophia.
