From what Clint had heard, from what little he had heard of the events after the fight with the Chitauri and Phil dying. He wouldn't get the chance to enact the revenge he wanted to. It wasn't enough for him to allow Loki to go to Asgard to be set to trial to whatever things they could dish out. He wanted him to suffer. Suffer for the loss of self, suffer for the loss of friends. He didn't think Loki had any friends, but that was beside the point. There was nothing in him that didn't want his revenge for what happened. He deserved it. Just like anyone else would in his position. Just like Coulson deserved a punch, any of the members of SHIELD who had to put up with this guy. His lips twitched into a smirk as he watched Loki start to push himself to his feet before loosing another arrow into an adjacent building before repelling in the god's direction.

He didn't care if he nocked another arrow and accidentally blew up a building at this point. He wanted to see Loki dead. He didn't give a damn what happened in the long run; if he died, if some innocent bystander got injured. All he wanted was to see Loki bleed. His feet made contact with Loki's chest, Clint moving to crouch in front of him as he flipped out his knife. "'d say it's good to see you, but then 'd be lyin'." Clint moved to attack him again, close range yes. But it didn't really have the same effect if he used a gun at this point.
