[Sam sees Dean and Cas holding hands]

Sam: so who finally confessed?

Cas: me, I made sure it was short and sweet

Dean: short and sweet?

Dean: you got drunk one night, came into my bedroom and yelled, "listen here you little shit, I have feelings for you and I know you have feelings for me too. so it's about damn time we acknowledge them."

Cas: like I said, short and sweet.
