This needs clarification so bear with me. From how I remember it in season 5 Christian shows Sun the dharma initiave group photo containing Jin, Jack Hurley etc. Meanwhile Flocke is standing outside, although we don't yet know him as Flocke, merely John Locke rising from the dead. Is this how it happened? If not, nothing to see here, if so are we expected to believe that Smokey can inhabit multiple people at a time. Cos even within the rules of LOST, I'm not buying it.
