Supernaturals (Universal mashup)

What happens when a ROB gets bored? Well he goes to the pitstop to meet truck-kun. But what if truck-kun wants you to help him with his problem. You see a certain merc with a mouth tracked him down (I know right it should be impossible, the one above all almost had me before I used the infinity stones to snap here)
As I was saying this merc (glares across the table) tracked down truck-kun because his life is so boring and he can't die.
This led to a deal and DP sneaking onto truck-kun jr. Lets see how it goes.
