Jack tried to stay optumistic as well for he didnt want to break down in front of the doctor. But it was really hard not to. Not when your lover, the one you loved for so long, finally got to see again was dying next you you and there was nothing you could do but hope that there was a miracle. Jack Harkness fought to keep the tears from coming out as he talk to his Time Lord. "Yeah. You sure do." You could tell he was fighting the urge to break down. That was the last thing the Doctor needed to see. Looking into the Doctor's eyes, he could see the pain that the Doctor was feeling. The immortal kissed his forehead as tears escaped and ran down his cheeks. 

"Owen! Its Arwen! I found it. The TARDIS has a cure! Im sending you a text of the things we need and how to do it. im sure that i can see what the ship has to help!" Arwen was all excited that she was able to find a way to save the Doctor. "See what Ianto can do!" She then hung up the phone and and started sending the message to Owen's phone while looking anywhere she can that might have said things needed. When finding wjat she could she ran like her life depended on it to get back to Torchwood to get them to Owen.
