Nice to get some clarification on the boat chapter. Obviously moving the boat chapter to Shenmue 3 retcon but I wonder if Yu always intended for Chai to reappear anyway. There's some old footage of Chai lurking over the moon (If I can find it I will insert in here) and then there's concept art of Chai doing the same thing in Shenmue 3. Could it be that he was always meant to appear again? His role as the only ally connected to Lan Di (that we know of) who knows that Ryo's in possession on the Phoenix mirror is rather unique.
