Finally caught up with this episode. I felt that it sacrificed character consistency to pave the way for some final showdown between Dean and Jack. Remember how Dean once vowed to kill Jack and Jack vowed to kill Michael even if Dean was the vessel? This is some cheap bonding to set up the emotional pay-off when the latter finally happens. Maybe Michael is currently latent (hence Dean's blurred vision) and later on, when Jack gets his powers back (hello Lucifer, we need to get Jack's grace back, please cough it up and disappear, for good this time), Jack'll have to make good his word... or not.

Still, the only thing that rescued this episode was Rowena and unasked questions about three anxious fathers in the fake-ER setting.
