There’s that too, yeah. Guy that shows him through the door to the field looks exactly like the actual guy who runs the place as shown in the beginning scene which is not part of this maybe he is maybe he isn’t nonsense. Tom Morgan is standing in the background, and I don’t think Flint probably remembered all of Silver’s random henchmen. Point is – there’s too much that’s out of place for Flint to know for me to buy the symbolism as anything but him going from the dark returning to the light that is his previous self and Thomas. Yes, there’s symbolism going on, but I’m not taking the Greek tragedy meaning out of it. James Flint McGraw is alive, that’s my bottom line.
Edit: Also, why in the hell would James be imagining Thomas with a beard? I know it’s a small point, but Thomas was always clean-shaven when he knew him.
