Sam was more angry then he thought he was at Dean. He knew that Dean was upset but didn't think that he had any right to just walk out like that.
Sam- "Where the hell were you dude?"
Dean- "Look, I had to get some air and think."
Sam- "So you leave us and scare us half to death?"
Dean- "I need to talk to Kat."
Sam- "You can't right now."
Dean- "Dude, you can't keep me from seeing her."
Sam- "She resting right now. She just had a pretty bad episode."
Dean- "Well is she okay?"
Sam- "She's getting worse. One second she'll be fine and the next it just goes down hill."
Dean- "We have to do something and I think I have an idea."
Sam- "Well I believe that I have already beaten you to it."
Dean- "What do you mean?"
Sam- "Obviously that was a spider kinda demon thing. And fire will kill it but also the venom from her fangs works as a serum to counteract the poison from her claws."
Dean- "So we kill spider lady, get the venom from her fangs, make Kat drink it, and she's cured?"
Sam- "Pretty much."
Dean- "Okay meet me in the car in 5 minutes. I'm gonna go and check on some stuff first."
Sam went out to the car checking to make sure that they had some flare guns and settled in the passenger seat. He patiently waited for Dean.
Dean ran up the stairs to check on Kat. When he walked in she had her eyes closed and was taking short breathes. The sight made Dean lose some of the color in his face. He had never really seen someone so close to death. He leaned close to her so that she could hear him.
Dean- "Don't worry. Nothing bad is going to happen. We'll go and kill that spider and then get you better. You better be here when I get back. We've been through so much and I don't think that I can lose you now. I mean come on, we still have plenty to work out and argue over and then make up afterwards. No matter what, one way or another you will be fine. If this one doesn't work I have another plan that will not backfire at all. I love you."
Dean leaned down and left a lingering kiss on Kat's lips. He took one last look at her and hoped that this plan would work. He slid the book into one of the drawers before exiting the room and going to join Sam. One way or another, Dean was going to save Kat, he just wasn't sure which price he would pay yet.
