As someone who's Sage path, having an affair with Jade but didn't share the video and avoided Tybalt's provocations (despite really, really wanting to kick the shit out of him), I'm somewhat optimistic about the meeting with her family. The Jade aspect will be awkward of course, but I think since Burke doesn't know about the affair, it wont be as immediately catastrophic.
One thing that bothered me, that might become a determining factor is MC doing the 'death by text' to Jade (too much of a bitch move) and I figure one of two things might happen with Jade because of it depending on if we get any chance to speak with her in private during the meeting:
1.) Jade gets spiteful resulting in blackmailing us or outs us. I'm leaning towards blackmail, due to her constantly claiming to not ruin her marriage. She repeats her 'Staying together with her unfaithful husband, for her family' argument fairly often and even doing so when you 'reject' her.
2.) By not starting problems with Tybalt or the video getting out, she accepts MC's relationship with Sage, maybe occasionally tempts us on the side and is willing to help out with the whole Maya/Josy drama. Seeing as Sage isn't her biological daughter, she might still try to make a move on him.
Another thing I do see being a problem during the conversation is if Tybalt is there and him trying to ruin everything by going on some sort of rant about the MC ruining everything for him and turning Jill against him, yadda yadda yadda; forcing the conversation to come to a halt. But I could also see the rest of his family dismissing him out right, particularly Sage, as I'm convinced that Sage is behind the troll accounts that harass Tybalt's Rooster post.
Going back replaying some of the other episodes, it becomes apparent that Sage really doesn't give two shits about him, though it does make the sex scene at the Preps party weird, as you basically have sex with Sage on her brother's bed. The two never interact with each other, at least that I noticed, so I don't see them being exactly on good terms, which will make any future family dinners interesting.
