Sometimes I think about Castiel being conflicted about having romantic feelings for both of the Winchesters.
Castiel getting sweaty palms and butterflies when he’s studying lore with Sam and being in awe of how brilliant the younger Winchester is and/or watching some kind of documentary with him about space and feeling his cheeks grow hot when Sam casually stretches out and rests his head on his shoulder.
Or Cas sitting out in the garage with Dean while he works on the Impala, passing him the tools he needs while listening to Dean singing out of key to whatever classic rock song he’s got playing on the radio. And if he has to excuse himself because the sight of Dean all sweaty and breathless gets him hard well…that’s his business.
But the Winchesters aren’t conflicted at all.
Besides, Castiel’s always been their angel and it all comes to a head one morning when Cas sleepily makes his way to the kitchen, lured out of his blanket nest by the smell of hot coffee and both Winchester brothers greet him with a kiss to each of his cheeks before settling at the table and waiting for him to process what just happened.
When he realizes that he doesn’t have to choose, that he can have this with them, he just kinda stands there with this dopey grin on his face.
“We love you, too, Cas, but your breakfast is getting cold,” Sam grins.
Castiel nods and takes his rightful place between both of the Winchesters.
