I briefly tuned in and he was talking to Jacob Wohl and some TCAP-wannabe, I don't know, but inside of 10 minutes they told a story about (a) a time where a guy and his girlfriend were trying to groom a girl; and (b) about another guy who boasted about his dick and it was "about 2 inches" when he sent them/the decoy a pic.
Ethan took the first one in stride (and of course vulnerable though Alice may be it's not the same as if she were a minor, but still) but he was visibly uncomfortable with the second.
