"Yeah, we'll do some research; we'll talk to people. I've already started talking to Angel about this, about what might be going on. I started when Faith couldn't remember you. We're going to find a door and we'll get access to that database. We'll find Giles, we'll find Wesley. We'll find someone, Dawn and I will fix this."
