[That brief contact is more than enough. Especially for Ironhide. He nods. Only to look completely confused when Optimus -- ah. Well. That explains it.]

[He just snorts -- more amused than anything. Had it been someone else listening in, he probably would have gotten up to crack them one over the head. Bumblebee gets the special privilege of grudging amusement, instead of cranky old anger. And he can't blame him for being concerned.]

Huh. Guess he earned it. Since he has all his parts together...

[Oh yes, he can hear that tone. No sense in not playing along, sounding as if he were considering turning down the offer. This is, of course, a sure sign he's feeling a lot more like himself.]
