Princess Bubblegum is a common sight around the labs. This isn't hers, but it's not unusual for her to come around and see what the other scientists are working on. Or for her to correct them where she sees errors. Or just lecture in general. She's used to being one of the most powerful princesses in her entire world and the undisputed lead scientist in every field. That may not be the case here, but she's still prone to acting like it is.

She frowns and leans over Jane. As often happens, she sees mistakes, ones that are easy enough to make, but also pretty easy to catch. Little things, but even the little things can throw off results enough to make them useless.

"I don't get it." She picks up Jane's pen and scratches some bits out, replacing them with the correct figures. "Did you have a whole army of lab assistants before or something? This is sloppy."
