Pretending to be angry, but not.

“Fuck you, Grue,” (1.5) 

Incredulous

“They’ve assaulted you!... “The only difference I see is that they deserve it and you didn’t.  I mean, I’m not smart like you guys are, so maybe I’m missing something.” (4.3) 

Stated like you don’t care

“No offense… Well, I’ll rephrase: I don’t really care about offending you.  Don’t shoot me though.  I just want to stop you there and say I don’t care about the science stuff and all the technobabble about how you did it.  It’s boring.  I’m just saying it’s kind of neat to see what a person looks like when dissolved down like that.  Gross, creepy, fucked up, but it’s neat.” (4.8)
