Yes, it was incredibly obvious, even before Vriska was actually declared his server. It was just too good a goldmine to pass up, and I'm sure Hussie had it planned from wherever this all began.
Huh, Tavros actually refuses to apologise to Vriska for being a cripple. Maybe Vriska's technique for forcing him to stand up for himself is working, whether or not she is actually trying to do that.
I'm betting Hussie was planning on this wording being used.
It's going to be incredibly sad if an upcoming command is "AT: Stand up for yourself." and he then falls on his face. It will be very very sad. At least he's trying.
Also, yeah. I'm genuinely wondering exactly what's going on in Vriska's head. Does she genuinely think she's being put upon as Tavros' server because he's crippled, and that she's responsible for that doesn't enter the equation? Or is she really just that huge a bitch to throw around statements like that to watch Tavros squirm? Laughing at him as she rolls his chair around and building the stairs in that ridiculous pattern suggests to me the later.
Of course, there's also Karkat's romcom explanation that she's being a huge bitch to Tavros in particular because she actually loves/pities him and doesn't know another way to show it. I'm not ready to put any stock in that one.
