Rico notices the alien clench his teeth, and smirks. He'd managed to stave off the worst of Rico's hit, but he'd still made him hurt.

"Did that hurt, creep?" he calls out mockingly, careful to regulate his voice so he sounds like he's barely exerted himself at all. The coppery taste of blood coats the inside of his mouth, and he spits it out on the ground. "You're a glutton for punishment, aren't you? Not too late to stand down -"

A paper bird flitting about the edges of his vision at the wrong time lets the kick at his ankle brings his foot out under him, but Rico recovers in time to land in a smooth crouch. From there he springs forward, jumping clear off the floor and barreling straight into Garrus's waist, bringing all his hefty weight to bear.
