I think that was part of the reason as well. That is why i don’t believe Adam and Eddy that this was the plan. They were still trying to work things out with Jennifer Morrison, but they weren’t willing to make her a producer for whatever reason. I think some actors just go with the flow and don’t care about that stuff, but some need that consistency and backstory information for their acting process and what was happening wasn’t working for her.
The problem being that i imagine the producers don’t want the actors to know what a mess they are in the writing process.
