This idea is ShiniestUmbreon101 but I came up with the scenario for Sam and Dean

Gabriel: an archangel appears to you with candy and you two get to know each other

Lucifer: you wake up chained down in head to a bed and you see the devil

John: you are his son/daughter and on a hunt with him partnered with him while Sam and Dean are together

Sam: He found a weird looking spell and wants to see what happens by using it on you, the surprise what a shock to all

Dean: You were down cause of something happened (your choice) and he decided to cheer you up the only way he knows for a while.
