Yeah, the plot with Elliot/Alicia was a really fun idea, and I wish I could have followed through with it. But I've been having so many problems being able to find his voice in my head to play with Ana.
I'm pretty sure Max/Jamie/Gus will be sticking around. Max and Jamie are used to being put on the backburner and coming out when they're needed, but Gus is the one that needs a bit of a push.
