Jack nodded to Ianto's question. "Yeah. That was the Doctor. He regenerated. But the Master seems to have appeared once again according to the Doctor. Arwen and I were in the Eye of London when we found out that the Ferris wheel's carts were set to blow randomly each time it moved. Arwen and I were able to make it out. Only to find out something shocking. But that I cannot reveal till we figure out more. But Arwen is more than we thought she was." Jack explained to the best of his abilities. "But if you want to stay, that's fine. But right now, the Doctor is sick and there is something in the TARDIS that made the Doctor sick." 
Arwen sat on one side of the bed as she watched the Doctor bury himself in the covers. It was interesting to see but it made her feel sad. She scooted closer to the Doctor and rubbed his arm with some slight hesitation. "I-i'm sorry you got sick. Anything I can do to help?" she asked hesitantly.
