Cisco waits for Felicity to get situated so that she's out of the line of fire and he takes a second to register just how ridiculous and stupid they would sound and look right now to someone who didn't know what was going on.

And he laughs.

"Okay, here we go..." he says, reaching for the doorknob again and startling a little when it's almost like the goddamned thing knows, because it thumps itself against the door again. "All right, come at me, bro!"

The door flings open and Cisco steps aside to let the robot dog angrily rush into the room. Cisco kicks the door shut with one foot and by the time he manages it, the dog turns in place and starts rushing toward him.

"Not today, Robomutt," he grunts, and Cisco swings the folded metal chair with all of his might, slamming it into the robot with a loud metal clang, and hoping like hell that there was enough momentum behind the swing to knock the damn thing over. When it wobbles a little, he's not sure it's actually going to fall over, but it tips and drops onto its side, legs flailing uselessly. Cisco drops the chair and raises his arms over his head victoriously, looking over at Felicity. "He shoots, he scores!"
