While Kate was gone Castle and Rease sat in the break room.

Castle was trying to figure out why Kate keeps kicking him out. "How come your staying with Kate, Rease?" Castle asked.

"My Mommy says It's because she can't control my changes." Rease answered sadly.

"What changes?" Castle couldn't help it he was been really nosy.

"My wolfblood changes Katie says her's is coming back and It's because of a Castle she likes. Wait maybe she said loves. Don't know." Rease says absently.

When Kate returned Castle pulled her into the observation room.

"What's a Wolfblood?" Castle asked Kate.

"I-I don't know why." Kate stammered.

"Rease told me Beckett don't play with me what's a wolfblood?" Castle said angrily.

"It's like a werewolf but they change on a full moon and whenever they want really the only tell they are one is purple veins and yellow eyes." Kate answered. "It keeps happening to Rease."

"What about you?" Castle questioned she knew he was close to finding out.

"It happened a couple of days ago. But I swear that was the first time since I was 14." Kate cried.

"I believe you." Castle smiled.

Once they had calmed down Kate and Castle went out to find all the detectives surrounding Rease.

Kate ran over to find her sat in the break room cowering in a corner. Hands behind her back and her eyes closed. Castle looked at Kate in horror.

"Katie is that you." Rease spoke up.

"Yeah I'm here. I'm right here. It's ok just tell me what happened." Kate said quietly.

Rease took at deep breath. "I was sat here and a girl came in asking me things, but I didn't know the answers. She said I shouldn't be here and it's her families territory. She said my family belonged somewhere else. That you belonged somewhere else because your a tame." Rease was crying by now.

Kate approached her slowly and picked her up. "Come on let's go somewhere quiet."
