2. The Gang Coping Without Leonard
One of the main things I'd like to see explored in series 7 of the Big Bang Theory is how the gang get by while Leonard is off in the North Sea on his expedition. We are so used to seeing Leonard, Sheldon, Howard and Raj take part in group activities socially that we very rarely see the quartet broken up. It'd be interesting therefore to see how the gang manage as a "trio" and how Sheldon, Howard and Raj cope in Leonard's absence. Leonard has often been the glue that holds the very social fabric of the group together and we can't help but wonder how this dynamic will change while he's away. Perhaps the first episode of series 7 could be completely dedicated to how the gang get on with their lives in Leonard's absence, and how they react when he eventually returns. Maybe they've moved on without him as a social circle. 4 months is a long time.
