Is there any possibility that Graham returns to show???

The writers have dropped hints that he might return. So, yes! There is possibility that he may come back.

Was so awesome if after he died he went to the fairytale land... and now Emma and Snow find him!

I really hope Graham comes back, but I find the possibility of Him coming is very slim

if anything he might come back as the huntsman in fairytale past. like eddy kitsis always has said "graham in storybrooke is dead but the huntsman in fairytale land is very much alive" if graham was to come back to life, i would like to see daniel come back to life as well. not just as a ghost figure like what we're gonna see in "the doctor"

the longer the show goes on the more doubt I have. it makes me sad to think about that though. but I still hope and wish he would come back more than anything

I heard the creators have neither confirmed nor denied that Graham will eventually come back. From what I've seen almost anywhere, that means yes.
