Stein jogged after the group of misfits casually keeping up. His legs, after all, did not tire, and he had a large amount of unfinished business involving those here. If they truly did wish to cure Ruby, then that might remove her insanity. And that, of course, would mess with Stein's plan. Luckily, he had the perfect distraction planned, and he himself would ensure Ruby didn't recieve the treatment she needed. "We should stick together. I don't know much of Witches, but I'm sure I can be of help somehow. And like I said before, it's best to stick together, right?"

Mia simply laughs at Weiss's blush. Her toy was a beautifu thing, so willful. Still resisting after so much pain. It was such a shame her toy would never become one of her special projects. However, soon she was sure Weiss would feel all the pain she wanted. Mia stopped moving as Weiss kept walking. The Black Blood leaked from Weiss's left hand and formed a long black sword as the Black Blood seeped into Weiss's face, completing Mia's control. This was going to be fun.
Weiss stepped out of the forest next to Yang, and stabbed Yang in the shoulder with the Black Blood blade. The Black Blood twisted her expression into one of savage glee, her horrorstruck eyes making the expression eerily unnatural. From her throat came her voice, although not her own, generated by the machine Mia had dropped in. "Hello, old friends." Black Weiss hit the startled Yang, sending him flying through the air onto the ground. "I think it's high time to end this. It's been fun, hanging out with you, but now that we've arrived here I have more important things to do."
