Jack had been trying to find out what had been affecting the Doctor, not realizing that the Doctor had fainted till Arwen had told him. The TARDIS had been working on the DNA matching while Jack tried to find out what infected the Doctor. Arwen just stayed with the Time Lord to make sure that if he was getting worse, she could try and find a way to help. While sitting next to the bed, she felt another feeling of familiarity. This was odd for this to occur more than once. This just started to get too confusing to her. Between what felt familiar and what was. 
Jack sighed in frustration, walking over to where the Doctor laid. Looking over to Arwen, she looked distant, thinking about what looked like millions of things that she had been thinking for a while. "Why me?...I don't understand. I was just an ordinary human, living life. Now look what's gong on...I'm being told I'm a Time Lord and that I may have a brother that I had no idea about till now." 
Jack listened to her, seeing where she was coming from. "Honestly. I don't know. But no one can escape who they are. There must have been a reason you don't know. Things like this take time, Arwen. At least you are knowing now then later in life." Jack told her. Arwen nodded slowly before standing. "I'm gonna...I'm just gonna go walk around..." She told Jack, turning around and walking off to go think. 
Harkness stood by his lover as he was asleep, waiting for him to wake. It took a few hours but when he woke, Jack had been going over the tests. Turning to face the Time Lord, Jack noticed how pale he was and him shaking. Sitting on the bed, he combed his fingers through his semi gravity defying brown hair. "It's alright. Your in the Medical bay still. You fainted." Jack then moved to where he laid with the Doctor, thinking he was possibly cold.
