If Morgan comes back they should have him to be a helper to his father Sonny and they're not at odds like the return with Jason and Sonny's deranged relationship.
I hope it is Johnathan Jackson! I would love to see the original Lucky! Also Frisco would be great! However my guess it that it could be Mac after his recovery from illness! I so love Mac! He is missed...
I thought it was Mac but saw a photo of Bryan Craig on the current set. Mac is back already. Showed up today, it is great he is back healthy and cancer free. He may be back in a dream to remind Sonny how he died from Ava messing with his meds and have him realize his meds checked. I hope he is back for longer than a dream but thinking that may be it.
