"I don't know," Kate says, thinking about it. "No, I don't think so. It's just how it is. I mean, I can't remember stuff I wasn't even there for, right? It's different than what happened to you."

She's honestly not sure if that would drive her crazy either. It probably would, she'd probably go nuts trying to figure out what had happened in her past and where things were going from there, but the way it is now, just not knowing what happened to her family after she showed up on that island, it's not so bad.

"I wish I knew if they were okay," she says. "But that's not the same."
