If he's at their level, while they've have went through transformations each jumping their power up. I honestly can only see another hand giving him godly power. Because I'll call bullshit if he has done it by himself.
I think season 7 is the weakest season of Supernatural. But season 8 introduced new concepts, ones I won't mention. But I enjoyed them stories. Linked to the great grandfather I believe.
My favourite scene would either be the Rabbits Foot one or when Death was introduced for the first time.
I loved Bad Day at Black Rock (Rabbits Foot). It was my favourite until The French Mistake in season 6. I laughed so hard at Dean and Sam, playing their Jensen and Jared, playing Dean and Sam. Having been doing acting for about 6 years at the time, was good to see.
I was talking to a friend. I think it's time to move on from the angels. I think they're keeping Dean and Sam in a rut.
