I can't remember if this was the case in the original game or not. can you unlock the secret episodes (refers to both of them. I can't remember the proper name for each) by playing all 3 characters simultaneously? or is it one of those things where you gotta finish each character's story from beginning to end before starting a new one? want to make sure before I put 30 hours into 2 of the stories just to find out I need to restart them...
