Arwen came back to that realization and thought it wouldn't be a bad idea to drink some or at least what was left. So Arwen nodded after the Doctor explained the whole ordeal. Plus she heard the brotherly tone in his voice. It was rather odd but she was willing to anyway. "Alright. I'll have what is left and I'll even drink it in front of you so you will have proof that I did. Sound like a deal?" She asked with a small smile appearing on her lips. 
Jack smiled, looking over to Ianto. "If you can get Owen to the couch then go ahead and go home. Thank you again. I'll let you and Owen know of the progress." Jack explained. Knowing that all they had to do now was to wait it out and see.
