He's not entirely sure she's not going to yank him back down by the back of his shirt, since that is clearly a move that she's okay with. Instead, she moves into position to cover him. He grins back at her, though it fades at the crack about his age.

Why does everyone ask him that? He knows he looks young for his age but... His thoughts are stopped by another round of fire and he gets his head back in the game. "I'm twenty-one," he assures her, looking over at her one last time. "And if we get through this, you owe me another drink for that."

He sucks in a deep breath and then he's off like a shot. It still feels like slow motion to someone who is used to going at mach speeds, but he gets lucky with the fact that the guy isn't looking in his direction and Natasha works fast to distract them. It feels like an eternity for Barry to actually get to the guy, which he slams into with all his weight. It's not much, but it's enough to knock the guy off his feet. Barry scrambles for the weapon the other man dropped in the scuffle and is rewarded with an elbow to the head that makes him see stars. Still, his fingers brush the barrel of the gun, just as the other man manages to get out from underneath him. Barry rolls towards the gun and holds it up at the man, just in time to discover he has another, smaller gun he's produced from nowhere and is pointing it at Barry.

He probably should've seen that coming. Oliver would've.
