Alright, just finished watching the vid. Tom pretty much argues that the whole thing was consensual and that both girls wanted him to be violent and film them. Which, alright, some of the messages seem to indicate that, so unless the girls come up with some really good proof, it's clear that this was a goonerXgoonete relationship.
BUT! Here is the big thing, he doesn't disprove the ageplay stuff at all! He acts like he does by showing some brief messages from Ellie, but never mentions the photos he took with her in a hotel, nor does he speak of how Lerix accused him of doing ageplay with Kai. His argument against the ageplay allegations is that he has messages from Ellie and Kai saying they would never EVER EVER EVER EVER do ageplay, so it must've not happened.
He clearly knows that the ageplay stuff cannot be disproven(because he does it), so he barely mentions it, flashes some stuff on the screen, and moves on to another topic.
