I think this could be a great opportunity to reintroduce The Colony to the story. We know that Sean went to The Colony, and we suspect that he thought that CJ was dead. Sean would have probably known about the "garden" locations in LA set up by the Other Tower. What if he reported this information to Marcus and the information was recorded? Eventually The Colony would have wanted to send out scouts to find these resources and gather them. What if the "freshly turned" person with the address in his pocket was a Colony scout? Granted, you would assume that Victor would recognize him, but it's possible he didn't know everyone, or that the turning-process made it hard to recognize him.

Sean might have also passed on info about the various safe houses The Other Tower set up, which could make for an interesting encounter as Saul, Victor and CJ get ready to head back to their base.
