I think Dean used to deny his fatherly instincts out of habit, but since Ben I think he's really afraid to get that close again. He treats Charlie and Kevin and Cas much more as siblings.
Charlie and Kevin, for sure. Cas... gets less mothering from him than a brother would. (I do use that word intentionally, because he did effectively serve as Sam's mom, and it shows in how he brothers.)
Whenever there's a teen hunter, I totally get the protective motherly vibe from him. It's adorable.
I prefer the idea of an angel who means well doing really creepy/problematic things out of lack of understanding about the human condition.
I don't want an evil Ezekiel at all. Evil angels outstrip decent angels by a mile at this point -- I'd like to see an unconflicted good angel for once.
Cas... gets less mothering from him than a brother would.
In the beginning, Cas was very much "other" in a more commanding, awe-inspiring way, though. And he fucked with Dean a little bit in the beginning, too -- a couple of the early S4 eps are Cas "testing" Dean or manipulating him. So I don't think the caretaking instinct was there for Dean until later, when they already had lots of other history.
He's totally got a more Benny relationship with him. It'll be interesting to see how the dynamic changes now that Cas is graceless.
I have my own feelings about Benny. I think their relationship was way more obviously ho-yay from the start than Dean's with Cas, but it was also a lot less complicated.
My fanon is they were totally fuck buddies in Purgatory.
Dean! It's not too late for you to get help! Not that I'm judging or anything.
Oh, man. Amy, remember the exhaust pipe fic?

I think it was deliberately written more relationshippy, but it lacked not just in Cassy subtext, but intimacy. Like, they'd barely circle jerk. That's why I have difficulty with Purgatory fuckbuddies, but less with the threesome. A LOT LESS (recs welcome).

The way they look at each other both during and post-Purgatory is so full of twinkling and heat! For me, anyway.
