[Pete hasn't seen Adam looking this drained since...well. Any awkwardness is subsumed under concern--which is in turn hidden by anger. You can tell the concern's there because he's herding Adam toward a chair as he scolds.]

Flark, Adam, if you'd told me you were feeling this out of it, I'd have walked! We don't need the Magus showing up because you're too tired to fight him!

[Pete's not entirely sure how the whole deal works, but Adam was complaining about being exhausted right before he turned purple.]
