It really did happen so fast. He heard the name, the instant recognition slammed into him like a wall of water. Blue.... blue... water. He didn't even grab the burrito, he just looked at her. Why didn't he recognize that voice earlier? Why did it take her calling out his name for him to suddenly realize who he was really talking to?
His cover was blown. The persona Blue had been the only thing keeping him from the snafu of possible authorities and people worrying over him in a way he couldn't allow to happen. What if word of this got back to the others? He would have to explain how he came to be homeless and why he couldn't get himself out of it without risking his identity... or lack thereof.

Her look was, for the most part, lost on him and he cleared his throat, gripping the bag a little more tightly. "Jack." he greeted with full understanding if not a little solemnity.
