Barry lets out a small laugh of relief when the door goes off and neither of them are hurt. It seems like a small victory, but it's one that he's definitely going to put in the Alpha plus column. "I'm good," he says when Lydia looks at him with concern. He pats her on the shoulder as a double confirmation.

He grabs his own PDC and begins moving after her. The smoke isn't super heavy, but it definitely stings when he accidentally inhales it. The closer they get, the more Barry can see that the door not only blew outward inward several feet, but it also nearly crumpled in half from the explosion.

They make their way out into the hall, where the smoke is clearing. It's just as pitch black out here as it was in the lab. He can see the swirl of a few moving flashlights down the hall. "How about we take the stairs?"
