I have recently started watching White Collar and think it's brilliant, but I noticed for the first half of season 2 that El doesn't seem to be there, all of her interaction with Peter is either in front of a green screen in which it seems that they aren't together and has been filmed seperately or it's a phone conversation as they put her in California and she is clearly green screened.
Can someone explain this? Was she working on another project or something?
