Well, Jill and Tybalt is easy; the live in the same mansion. As for Sage and Tybalt, the likeliest explanation is that there's a Greek council for the sorority and fraternity Presidents and Sage has to deal with Tybalt at the meetings so she knows what he's like.
Man, I knew I phrased that one poorly.
So what I was really trying to figure out was the connection between Sage and Jill, with Tybalt being the "extra" in that sentence. I mean, sure, you could argue Sage is just a cool girl, which would be true, she seems like good people. But I still got the feeling from the Rooster that Jill and Sage know one another to some degree, and Sage stood up
for her rather than
to Tybalt. I mean, creeps are all over the Internet, and while I don't use much social media anymore, I can't really see myself jumping on random people's threads telling people off unless there some
serious creepiness going on.
I mean, yes, Tybalt's creepiness is way up there, and if you told me that's the reason for Sage's comment I would hardly argue with you, but I just got a gut feeling, you know?
