Hahahahahah!!
I know how it feels. The whole scene felt so light, like a silent fart or something. Weak way to kill off a supposed major character. He'll be back.
Aside from that, the episode felt a bit too fastfoward at times. Like Dean suddenly finding Sam's location after the short drive in the middle of the night, the house suddenly being burned down, Bobby investigating the hospital while showing no sign that he was saving the sheriff… and some other minor things. Hopefully the Leviathan arc doesn't drag too long.
