[As soon as Shinichi interjects, every sign of impish joy is lost from Rex’s chiseled features which contort back into their unfriendly default state.]

And I’ll Aldrip-you a new one if you don’t get the hell away from me…!!!

[He mutters, signaling for Shinichi to back off. So the little guy is most definitely a parasite, something like the creepy crawlies on Mars, which Rex knows full-well that he isn’t at all resistant to. In fact, it’s the one thing that keeps him from shoving the other boy away entirely, since avoiding physical contact is now a necessary precaution. As far as a choice for a host, Rex haughtily considers himself to be a great candidate, being at such a peak physical fitness. It also helps that in spite of his downright awful personality, his looks help him get away with a lot, especially when he isn’t wearing his supersuit.]

It’s slang for “masturbate.”

[EVIL?????]

Yeah I’m new! I was just on the job. A job that nearly killed two of my teammates and some other guy!

[He means in Invincible. Rex may not like the guy, and he’s not showing it now, but wow. Watching him go down like that was harrowing.

Hopefully he’ll survive.]

If that giant hairball from space also made it on it’s way over?

We are. So. FUCKED!
