When I watch Alias I like to see who was not shown and decide what part they will play in the next episode. Irina was not in Part 1 wouldn't it make sence for her to be part of Part 2? Also, if Sloane and Sark are plotting together, wouldn't it make sense for the better strategists: Jack Bristow over Sloane and Irina over Sark to ally together once again to figure the plot out? The one problem with this is if Irina is behind the overall scheme. What do you think?
