Castiel entered the diner and found the Winchester brothers in a booth by the window. They had food out in front of them and didn't look to be in a rush so he sat beside Dean. "You summoned me?"

Sam and Dean shared a look then moved their plates in front of Castiel.

"We need you to settle something for us."

Castiel looked down at the plates. One of pie. The other was cake.

"I don't understand. This was your emergency?"

"I told you we were wasting his time," Sam said.

"Shush. It's time for Cas to pick a side."
