Wash doesn't bother to reply to the comment, instead waiting for Athena to hop onto his shoulder before getting to his feet.

"I'm sure." His tone is flat and a little edged - he's not going to argue about this. "One, I'm fine, and two, if I needed healing, I'd go get it from someone who didn't spend the first part of the fight hanging me out to dry."

It's not the phobia at play, or machismo - it's the fact that Rezo has made an incredibly bad first impression and Wash hasn't seen anything from him to revise that yet. Why accept medical help from someone who was perfectly happy to watch you get your shit wrecked in the first place?
