I remember him buying a BFG in the opening scene at a bar, but don't remember what you're referring to...
If i recall correctly first scene was a 1 year flashforward, celebrating his birthday at that gas station restaurant
Correct. Proving he doesn't die or go to jail (and it was Dennys, lol)..
Unless they do a MASSIVE fast-forward in the next 8 epsiodes which I doubt they would considering he was 50-51 in episodes 1-45. I doubt in the next 8 he'll go from newly 51-52.

You don't pay close attention to detail.
