No doubt she's chosen her words very carefully (read: manipulatively), but I've heard more than one story about Max's sexual sadism to know that he's got a very fucking questionable understanding of the word consent. One girl I know used the R word specifically. Grain of salt, sure, but I had no reason to doubt her. Girls around town know not to take anything Landis gives you on a night out the same way we knew not to go to Harvey's hotel room for a 'meeting'. Allegedly, of course.
ETA: I'm downright surprised no one has tried to bring charges against him in the past. OR, rather, that we haven't heard about it. It's his Mom doing most of the shielding btw. She's the power in the Landis house nowadays. Which is a shame - professionally she's a fucking hero.
