I would say that with the way this current regime wrote off AJ he's not coming back. But that doesn't mean it couldn't happen, obviously. I, personally, would LOVE if AJ came back. I doubt they'd get SK, but that doesn't mean another actor couldn't do the character justice. Frankly, the whole SK-thing pi!!ed me off. There was so much great and excited anticipation from probably 99% of the fans with his return that the disappointment I felt at what they did to the character just about did me in permanently. 

I, too, would love if they brought back Jake, but I'd like Lake to be in a full-fledged relationship if it happens. I don't want them to "get together" while looking for him, or solving a mystery regarding him. I would like them to go look for him while they are firmly already a couple. 

Fluke AND Luke just need to go and stay gone.
