Thief of Void pulls off the backstab. Makes perfect sense - the previous scene with HIC even has Roxy lying there behind the Condesce while the Condesce menaces the other three.
Whoever guessed there'd be a flat-out Undertale direct reference/homage in there wins the pot, and is possibly secretly Hussie's secret account for monitoring this thread.
Karkat may look like he lost levels of badass, but to be fair he was fighting the leprechaun with alllll the luck. Karkat actually beating him was actually quite a coup. Also, I think Clover is now in horseshoes with Karkat - he might enjoy bondage a bit too much.
Similarly, Dad may have a new disciple in Arquiusprite.

This is not the first time Dirk's been decapitated. I bet he'll pull through.
LE is probably succumbing to Caliborn's desire to just fuck around in combat, since he's basically invincible. I mean, he *could* have just opened with a solar-system-busting lazor instead of doing a single-person-blasting one followed with ineffectual street fighter moves. I'm kind of surprised to see the Time Stop shenanigans working on him though. Lord of Time and all that.
