I don't even know why would they assume that Jacob has balls to even try something with Sage, when Tommy of all was so impressed that MC made a move on Sage in the first place.

.
and Josy immediately showing up behind Maya is more than enough evidence for Tommy to know that someone fucked both of them at the same time. I mean I can accept that Josy parents just assume that Josy and Maya are just friends.

but I will not buy it that Tommy didn't know

, or at least suspect it that they regularly eating eachother out

.
so in short, I don't think there is a way to talk themself out of this
What I simply want is MC tell tommy to fuck off, in a I do whatever and whenever I want way.
