Lorna was saying things and all of it was basically telling Jubilee she could keep the dog. Her mouth formed a smile that transformed into a grin and Jubilee was nodding enthusiastically, "Oh my gosh, deal! I'll totally take care of Ryan and all his needs. I've been doing better, he hasn't eaten anything else and I'm totes sorry about the poop. Like, it won't happen again, I swear."
Because she meant it. If she could keep the dog and not have to keep a secret, she'd do whatever it took. But she knew she had to ask one thing, "Dr. Bradley won't actually like...do evil experiments on him if he wanders into the lab, will he?"
