[Thundercracker looking up finally gives Jadewing a chance to read the writing on the collar. An unfamiliar mech's name, what he can only assume is an address, and some other information. But the part that makes his optics flash bright in surprised outrage for a moment is comprehension of what the collar is; it's marking Thundercracker as that other mech's property.

He forcibly calms himself, though; someone had to keep a reasonably cool processor in this situation. He can't erase the look of bafflement, though, and that, he feels is totally justified.]

Of course I'm allowed. In fact, if anyone ever tried to stick something like that on me, they'd find themselves on the business end of my weaponry.

[Which might call TC's attention to the fact that Jadewing is indeed armed, as well as the fact that he shows no signs of abuse whatsoever.]

Why would I have one in the first place? And why do you have one?
