The way Jack put that was somewhat strange. 'feeling a familial tie'. That, combined with the fact that Jack was purposefully being vague, just reminded Gabriel that he and Mohinder had been wandering around in the dark for far too long. If people were keeping information from him, then they couldn't be too mad if he got it through other means, right? He took note of what Jack was wearing- if he got a chance later, maybe he could use clairsentience to find out what had really happened with Peter.

For now, though, there wasn't much to be done. He'd let Peter try to work it out, and if he couldn't, Gabriel would hear about it somehow- either through the news or from Peter himself. Jack was right, the whole family barely knew him as anything other than a monster. His presence probably wouldn't be wanted.

Jack's insistance that he their help took some of the sting out of that realization. It also didn't hurt that he launched immediately into talking about pocket dimensions, which took Gabriel's focus immediately. "So how do these pocket dimensions pop up? Are they like alternate timelines? Different ways a future could've gone?"
