Thanks for that. If they follow the book at all Lloyd is a physicist that works for the CERN Large Hadron Collider, so Simon could be Theo who works with LLoyd or maybe he's one of the people that doesn't go through the flash forward and recruits Lloyd to work with them. The book is amazing, I just don't think that they are using much of the plot or characters, just the general idea.

Besides Jack could so take Joe Fiennes.
