Sorry, I posted before I was done because my first post timed out and I had to re-type everything. Regina obviously knew that Graham had started to remember who he was because he had figured out where the vault was where his heart was locked away. It didn’t seem like Catherine had figured out that there was a FTL yet – she just seemed to realize that she and David never really loved each other and was content to just leave. But I wonder if it was inevitable that once she started to change the course of her life in Storybrooke that she would meet Frederick gym teacher and then it would only be a matter of time before she would also start to have flash backs – because Regina was certainly very bothered by the fact that Catherine had decided that she didn’t love David and was leaving, and she is obviously the one behind her disappearance.
