HEY I JUST REALISED (possibly this has already been talked about by everyone, but HEY I JUST REALISED.)
IF URIEL HAS BEEN WORKING FOR/TOWARDS LUCIFER'S RELEASE ALL ALONG, THEN WE CAN'T REALLY TRUST ANYTHING HE'S EVER SAID.
EG. WHEN HE SAID THAT SAM'S POWERS WERE UNIMPORTANT AND INSIGNIFICANT AND EVIL.
OH PLEASE LET IT ACTUALLY BE THE OPPOSITE.
OR AT LEAST IMPORTANT AND INSIGNIFICANT. I CAN LIVE WITH THEM BEING A BIT EVIL, WHAT WITH MY THEORY THAT DEMON POWERS = NECESSARY FOR SAM TO BREAK THE FINAL SEAL AS IS HIS DESTINYYY.
