If he wakes up at all.. really hope they won't kill him off.
In any case, I love seeing him as the anti hero of the show. In S1-3, he was clearly the most powerful of them all and would have been unstoppable if had gone fully chaotic evil but he was more like a trickster and did more good than bad and mostly helped everyone who needed it for a small price. Compare that to Regina who wasn't even close to as powerful as the Dark One and she killed a lot more people... usually undeserved out of spite.
