Ok, so is anyone else noticing how similar Liz and Sam are to Robin. I'm thinking Jason is trying to find someone who looks like the woman he has loved all along but feels he can not have. First because she was gone and now because she is involved with someone else.
Truth of the matter is Jason's most intense memories, the ones who held the most meaning for him were the ones he remembered first were about Robin. Seeing her, talking to her, touching her, kissing her they were about them. The writers also were pretty clear that these were suppressed memories, things that he kept buried deep inside.
Sounds to me like a classic case of supression. Jason may not realize just yet but he is looking for Robin and one day all those feelings are going to come back and well let's just say I can't wait to see it. Now that's a story worthy of daytime and rushing home to see.
