I'd like to see Max and Alicia back (with all the angst and secrets and pain). I'd like to Michael!Dean for a good few eps (more than demon!Dean) and then I want a proper bro-mo reunion with an eventual conversation about possession with some Gadreel acknowledgment. H/C is a must. More Sam and Rowena and fate. If we're wishing, why not bring back Sully (but only ONLY if they don't kill him off) or positive supernatural creatures like him. I'd like to see Sam and Mary together a bit more, I feel like we've haven't really had much of that.

And if we're wishing why not some wet-and-in-the-water boys. Far too little of that.

I don't want for much at all ;)
