Don’t you think it’s strange how Kanaya let Rose turn into a drunk over the last year?
KARKAT: I THINK IT’S TIME WE HAD A…
KARKAT: WHAT DID YOU CALL IT?
KARKAT: AN INTERVENTION?
DAVE: for rose?
KARKAT: NO, NOT ROSE.
KARKAT: WHY WOULD I BE TALKING ABOUT ROSE?
KARKAT: SHE DOESN’T HAVE A MAJOR PROBLEM THAT SHE NEEDS TO BE CONFRONTED ABOUT BY HER FRIENDS BEFORE SHE FLUSHES HER WHOLE LIFE DOWN THE GAPER, DOES SHE??
DAVE: uh yeah kind of
KARKAT: WHY? BECAUSE SHE LIKES TO DRINK THAT GOOFY HUMAN SOPORIFIC THAT MAKES HER A LOT FUNNIER AND MORE CHARMING THAN USUAL?
KARKAT: HOW IS THAT A PROBLEM?
KARKAT: I CAN HARDLY CALL GAMZEE A FRIEND ANYMORE. WHO KNOWS IF MY FRIENDSHIP WITH TEREZI WILL EVER BE WHAT IT WAS BEFORE. I USED TO BE PRETTY CLOSE WITH KANAYA, BUT NOW SHE AND ROSE NEVER LEAVE EACH OTHER ALONE FOR MORE THAN A FUCKING MINUTE.
Well, here’s a possible explanation! From Act 5.2:
TT: That’s thoughtful of you.
TT: To strive to pacify me as I scuffle down this black corridor.
GA: Is That What Im Doing
TT: Is it?
GA: On Second Thought
GA: Thats Not What I Want To Do
TT: That’s a pity.
TT: Who will make sure my soul isn’t forfeit in service of gods then?
GA: I Hope That Doesnt Happen
GA: But Id Rather Not Get Stuck In That Kind Of Pattern Again
GA: So If You Want To Wreck Turtle Villages And Tear Your Planet Apart On The Counsel Of Dark Gods
GA: Fine With Me I Guess
TT: What do you mean, “again?”
GA: Ill Do The Thing You Do When You Dont Say Anything
Kanaya might still be afraid of HELPING ROSE with her problems because of what happened with Vriska, fearing it might accidentally turn into a pale relationship!
and it’s not just that she wants rose flushed, either. rose at her most (self-)destructive is similar to vriska, and kanaya doesn’t want to get roped into dealing with that again and being similarly disappointed.
