[Damn it, Rei, you just had to go and tell Sousuke about Rin's own moment of stupid, didn't you? The only good thing about this is that maybe it clears up the topic that much further to him, helps him better understand why he's so involved-- he started it, albeit not intentionally.]

Idiot. [A huff, and he averts his look from both Rei and Sousuke, suddenly a lot more self-conscious. But at least he lets up on Rei's neck a bit, though not enough that he can easily escape.] I was trying to make you see how dangerous it is to go acting on your own, not to give you even more dangerous ideas...

[Ah well, too late for that. All he can do now is to try and fix what he messed up, so he shakes his head to snap out of his own guilty conscience and focus on being proactive, looking up at Sousuke.]

You see where this is going, yeah?

[The "we're going to have to keep an eye on this one" goes unsaid, trusting Sousuke to be able to read him.]
