He would much rather be with someone else, but Clint's wariness of Anna beats out his dislike of her. So he's going to stay close and maybe figure out what the hell she is. Not that he expected to get much out of a woman who could withstand multiple arrow wounds, but he can certainly try to talk it out of her. Clint's last line of defense is how big his mouth can be. He can try to chip away at her with his ability to be obnoxious. Anna, beware.

"Sorta. If you count waking up walking around like a zombie in the wounds while you bleed out being out here then yep." He's not trying to be sassy, but it's happening without him really realizing. She has Clint on edge and so it's sort of a defensive tactic he's adopted it. "We still have to talk about it." He's referring to her arrow trick in the attic.
