"Wrong answer," Sitwell informed the guy who just threatened to kill not only an Avenger, but this Agent's girlfriend. This was as good a time as any to give his training a field test-- how much better could it be than just one guy? It took him two steps to gather the momentum he needed to launch himself Loki's way, throwing his arms out like he meant to full-body tackle him but then tucking in tight to keep out of the blast range of that weird stick he carried and hit the ground instead, kicking a leg out to sweep him off his feet. Where his hands planted on the ground, the sun hit them just enough to make them blister, and Sitwell could quickly smell the burn of crisping meat bowed this close to them. Luckily, he was fast, really fast, vampire fast, and could throw his weight and shadow over his exposed skin, pushing himself up to turn that arc of his foot into am extra encouraging kick to Loki's gut. For a second, he didn't feel so stupid and exposed for not carrying a gun.
