Just something small that I caught: I don't remeber the title of the episode but its the one where Faraday talks to Desmond and gives Present-Day Des a memory. The thing that bugs me is that Desmond comes out of the hatch in his hazmat suit. This might seem like nothing but Kelvin never let Desmond leave the hatch (I think theres a line in season 2 thats something like "just let mr go out there kelvin, just one time, i haven't seen anything else for almost three years " or something like that.) and its unlikely that this was after Kelvin's death because Desmond would know by then that there was no need for a suit and 815 would've already crashed. So wouldn't Kelvin answer rather than Desmond.
So... What'd'ya think? Alt timeline Des?
