The sensible thing would be to get out of here and revert to plan "avoid everyone until we're through this bubble." You've seen how scary-violent trolls can get. On the other hand, Karkat. You've been increasingly aware of your own Karkat as a potential makeouts friend for months now, which might be just a lack of other options who aren't a) your ex, b) your sister, c) dating your sister, d) the Mayor, or e) COMPLETELY PSYCHO, but despite the poor reasoning it's still a thing. Your Karkat has seemed pretty oblivious. Evil Karkat, though....
