Y/N and Lucifer (in Sam’s body) are sitting together on the couch, talking quietly. Dean is in the kitchen, trying to focus on making dinner but clearly distracted.

Dean: (Walking into the living room, trying to keep his tone neutral) “Hey, Y/N, can we talk for a minute?”

Y/N: (Looking up, sensing the tension) “Sure, Dean. What’s up?”

Lucifer (Sam): (Watching Dean carefully) “I’ll give you two some space.”

Dean: (Nodding) “Thanks, Sam. Or… Lucifer.”
