You were in a bloody starship crash (and it's good luck for you that Julian doesn't know about your crashing a starship into San Francisco, or he'd be far less willing to help you), that's probably enough to do it.

Wouldn't it be easier to let him help you? Damn but you're a stubborn one.

"You'd heal faster if you'd just let me help you. I'm still offering." It's an olive branch as much as anything. Julian knows who and what you are, and he's still willing to help.
