Haha. Oh wow... Wowza. I don't think you'll have to worry about Jayvn doing anything like that. He's much, much more concerned about perfecting and battling alongside his Eevee Evolutions.
Yeah. She is. The old Jen from the first RP I used her in she killed two people in the first three pages. XD Of course, those people were soul bound, so when she killed one of them, the other one died as a result, but she knew about the bond going in. All because someone stole Dusk from her. Yeah, don't mess with her Zorua.
XD Actually, Jen and Miharu have been together in another RP. But it was rather short lived. And Jen was a little more serial killer/rapisty. Yeah, I toned her down a little bit. :D
