If it's at all like the HYDRA from my world, there will undoubtedly be other cells, off shoot organizations, and possibly infiltration in other agencies. They likely wouldn't have moved at this point in time if they weren't in a favorable position. It sounds like you've got a good team with you, though. You all helped contain millions of lives from being destroyed this time. I'm sure once a way back is found or you end up there, you'll give 'em hell.
