Lydia takes a deep breath to steady herself and calm her nerves while Barry starts taping — oh God, that's so precarious; what are they doing?! — the bombs to the hinges of the door. Fifteen feet. Five yards, that's easy enough. There's rulers and meter sticks all over the place. A meter is just shy of equal to a yard, so they'll actually get slightly more distance out of it if she uses that.

Making her way around the table and back to another one with her PDC in hand to light the way, Lydia grabs one of the meter sticks off the wall where it's hanging neatly with plenty of other tools, some of them seemingly random, and she heads back toward the door. Giving Barry a wide berth so that he isn't distracted — plus, that adds more distance between them — Lydia measures five meter sticks away from him and then backs up another foot or two to the nearest table without being too close.

While he's finishing up, Lydia's moving lab stools out of the way and pushing or moving equipment off the table itself so that they can flip it. Fifteen feet doesn't sound that far, but now when she's looking, it feels further than it is. Her stomach is in knots already.

"Yeah, yeah...as ready as I'm ever gonna be, so we better just do it before one of us changes our minds," she says and gives him a look that says she's pretty sure that person will be her. "Go, I'm ready. I'm ready."
