Kol and Katharine
Kol looked over at her with curious brown eyes. "Oh? Who were you before, darling? We might have quite a trek so feel free to enlighten me." Time, experience, and a certain little witch taught Kol to ditch expectations as well. He learned he didn't need the approval of anyone to be who he was and while the lesson had come with dying twice, he was glad he'd learned it.
At her question, Kol shrugged. "The normal vampire parlor tricks. I have the heightened senses, the strength, the compulsion, and of course, the fangs. Though I'll keep those to myself unless you ask nicely." He was teasing. He would need to feed at some point if they were trapped here long enough, but he wasn't planning on snacking on Katharine.
"I've died three times," Kol replied. "None of them pleasant, but who is surprised? Death isn't meant to be pleasant." Worrying about surviving another was a legitimate concern, especially here. Kol knew there wasn't much that could kill him, but others? Oh, there was plenty.
"Well, let's hope you don't have to find out. As to why my family always tries to kill one another, let's just say we have differences of opinion...a lot." And Klaus was also an controlling son of a bitch, but he wasn't about to dive into that mess.
