Things that were questionable or just plain stupid - my problem with this episode was that it made no sense to leave Jack alone in the Bunker, now that he has his powers back and possibly some of Michael's and needs time to get used to them again. And for Cas to go off and leave Jack seemed uncharacteristic, it would've made sense for Cas to be there with Jack - Jack could've still gone into town and got friendly with the teens etc. I really hope Jack isn't on a downward spiral as my poor battered heart can't take that on top of the news!
