If Dean had a choice— it would be to never have to work with you again. And, as much as he hated it and would never admit to this ; you were useful. In your own.. very annoying blood-sucker kind of way.

And, this is exactly how you ended up in this situation. You, being reckless and refusing to even let Dean get a word out. “I’m going down there, who knows how many creepy crawly.. whoever crawls kind of things are down there.” Cue an annoyed scoff from the hunter. “You let me go down there alone and I could die a bloody death.”

God, you annoyed the hell out of him, “Then I’ll leave you to your death.” Yet, he’s still following you. How ironic.
