Phil did notice the gun. He wasn't really sure what to do with that knowledge. It only emphasized that Clint was clearly in some kind of trouble. Phil's urge to help was overwhelming. Clint needed help and he'd come to Phil. Phil would have wanted to help, anyway, but being asked only intensified it.

"Maybe I want to know that you're here. I don't mind having a guest, Clint." It would be easier to offer more help if he knew what was wrong, though.

He sighed and moved his hand down quickly to slip his hand under Clint's shirt and grab the gun. "So tell me what this is for and what's really going on. Please."
