AAARGH this is messing with my head!!!!
It could be possible, I just didn't think he was like that, he seemed really dorky and innocent as a Turk. Almost like he didn't belong in the Turks.
But if he is Yuffie's father, then what does that mean with regards to Godo? Would he think he is Yuffie's father? Did he get duped somehow?
No I think it's more likely that Vincent came across Yuffie's family at some point, them being pretty authoritive in Wutai and all. This is slightly off-topic, but Rosso seemed to know who Yuffie was in DoC (WUTAI FLEA!!!!), so obviously the family have a lot of status even to reach Deepground in reputation.
