This isn't going anywhere close to the way Karkat had wanted it to. Why is it she can never make things simple for them? The disbelief is more frustrating than any demands for him to leave would be, any anger or tears -- he's changed his mind. It'd be easier if she'd just stabbed him.

His eyes are reflective, like those of a nocturnal animal; they gleam when the moonlight falls on them at a certain angle. His lip curls in a snarl, his shoulders rise, his presence growing tense and angry -- because anger has always been the safest reaction, the easiest defense, even more so where he just came from. Floundering and hurt as he is, it's almost unconscious of him to fall back on it.

"Yes, those ones. I really hate to be the one to tell you this, but I'm not fucking invincible, Ruka! Much as I would like to laud myself as the pinnacle of all survival and evasion, I make mistakes. I screw up. And it just so happened that I screwed up about as thoroughly as one can screw up. I screwed up harder than you screw up a snot drenched Kleenex before tossing it out. You know they have these things called depowering rays? You know what a trap is, don't you? Do I have to remind you my powers only work on twelve people at a time, and entire SWAT teams tend to consist of a little more personnel than that? That I'm only one person?" The words are ground out through his teeth; there's a desperate edge to them along with the aggravation, though. Please believe him. "I'm sorry, okay? I'm sorry. We knew this might happen. We knew it was a risk! I'm not lying to you about this, look--"

And from his sylladex he pulls a device, cracked and broken -- a collar? A power nullifier, in fact.

"Where do you think this came from?"
