Terezi really has no idea what she did to set off this Rose. She's clearly older than the Rose she knew, but whatever happened to piss her off this much, Terezi hasn't lived through it yet. She notes that Rose is trying to pull Dave away, and the protectiveness of the gesture is kind of sickly hilarious. She wouldn't dream of hurting Dave. Ever.

Still, she holds her hands up, showing her palms in a gesture of good will. "Okay, friendly warning for you, Rose: if you start trying to remove limbs around here, you are going to have a lot of Peacekeepers to deal with. Lots of humans with the authority to throw you in a cell and possibly torture you if they don't like your face. Neither of us want that, so listening to Dave is probably your best course of action until we can figure out what future me did to ruffle your eldritch feathers."
