As most of us know, Davi Jay has been supposably been cast as "Tony". His character has not yet appeared, and according to sources will make his appearance in Episode 12, after the arrival of Abraham's Group in Episode 10. This raises the question is he Father Gabriel Strokes, the final survivor met by Rick's Group on the road before Alexandria. Since the show uses fake names often in casting calls for notable comic book characters, I would say yes due to the time of his appearance and his facial appearance. I could be wrong, though, as he could just be a random survior, but I find that highly unlikely.
