Wolverine ends up changing history from 1973 and manages to change the outcome of the future. In the scene where Wolverine gets pulled from the bottom of the bay and onto the boat, General Stryker (Mystique in disguise) takes Wolverine from there.
Most will agree that she probably does this so Wolverine wouldn't have to suffer being taken by the real General Stryker. Does that mean that Wolverine doesn't end up in the hands of the real General Stryker at any point in time from that day and the future when he returns? If so, wouldn't that mean that he never gets the adamantium injected into him? This could only mean that Wolverine ends up returning to the future having only his claws of bone because he doesn't go through the adamantium procedure. Is that right or there is an alternate possibility.
