Sure, she fckd up by not being honest about it going as far as ‘oral’, but as she tried to explain to him (time and time again), she didn’t want to do that for the viewing public that didn’t ‘see’ what happened. 
 
In my opinion, Zane is more culpable ‘for her mistake’ because he KNEW she still had feelings for him and he used her to get his rocks off, then ran to Dylan to save himself when he feared he’d be found out. 
 
Dylan’s response by putting her on public blast and slut-shaming her was horrific!!!  Watching ALL of the guys laugh as the gals (all but vile Kaylah who started laughing, too) sat in shocked silence tells you all you need to know… as well as Taylor’s confessional… that the attack was pre-planned and ALL of the guys knew it was coming.  Dylan’s ‘apology’ afterwards about ‘being said in the emotion’ is a bald-faced LIE!!!!!  We didn’t get to see it, probably because the producers are trying to clean up their favorite narcissistic POS, but I’d almost bet anything that Taylor pushed Dylan hard that whole afternoon to do what he did just to CAUSE more drama.  I say that because he just couldn’t help himself, craving the chaos, and we saw him asking if he was going to do it.  VILE people!!!
