So I finally got to see "Unending" (or most of it at least on a local station here in Boston today). Forgive me if this is a noob question that's been answered a thousand times already, but there's one thing that bugged me. Why aren't there now two Teal'cs running around? An "Old Teal'c" and a "50 years younger Teal'c"? Teal'c was protected from the reversal in time, and stops Sam from initiating the time dilation field in the first place, so shouldn't there be a "Present Day Teal'c" already on the ship along with "Future Teal'c"? Or shouldn't Future Teal'c at least have just disappeared or something, leaving only the original Teal'c? It seems like the least likely outcome would be for just Future Teal'c to be remaining in the present (now altered) timeline. Did I miss something?
This is why time travel gives me a headache. Otherwise, enjoyed the episode.
