I think the most interesting interaction is between Jack and Locke.

In #1, Locke looks very pleased with himself and Jack has a look of "what am I going to do with you?" about him.

In #3, Locke looks like a kid who's just been sent to his room while Jack looks like he's not pleased but has meted out a fair punishment.

Also, in #3 note the lily and skull in front of Hurley, Miles, Ben and Frank. Additionally, Hurley is looking "heavenward". Also, it appears as though they are the only ones not interacting with everyone else; does that mean Ben, Hurley, Frank and Miles will die? I really hope Miles and (especially) Hurley make it the end.
