It's ok. Adam doesn't notice what's going on immediately either.

Like Axel, he's caught up in a memory that he didn't know he had before now. Running away from... something. In a cave. Was that a three headed dog?!

Adam jerks back into reality, glancing around and trying not to look too conspicuous as he sees Axel's still out of it. So he'll just take his arm, and... hope that'll help.
