Re: John Connor's existence POLL
Sarah Connor was all tarted up and ready for a fertile night on the town before Arnie showed up. The first John Connor must have had a different father. As soon as John sends Kyle back in time and Skynet sent the Terminator everything is changed. There is a different John Connor, but one who knows what happened to his predecessor (not all of it, just becoming resistance leader). It was a miscalculation on the effect of time travel by Skynet just as Marcus' human nature was a miscalculation in TS.
If John Connor had been killed by the machines at any time, somebody would simply have stepped forward to replace him, perhaps even adopted his identity. John Connor is a symbol.
He was a dreamer, a thinker, a speculative philosopher... or, as his wife would have it, an idiot. ~ Douglas Adams
