Unpopular opinion, but Bucky would not call you "doll."
The petname is cute and all, but I firmly believe Bucky, especially Bucky now, would not call you "doll." 40's Bucky, maybe, but post Winter Soldier Bucky? Not a chance.
No, no, current Bucky, he'd pull out rare, but sweet and gentle petnames. He would normally call you by your name, or a different version of it that only you allow him to call you- but no, never "doll."
Not "doll," but you could be ranting about an interest of yours, maybe you slowed your talking, thinking no one was really listening. And Bucky would tap your cheek just once, mumbling, "and what else, sweetheart?"
Not "doll," but you could call his name, just to get his attention for something you may need help with- or even just asking him a question. And Bucky will immediately respond with, "yes, my love?"
Not "doll," but he'll occasionally replace your name with "baby" just to get your immediate attention. Sometimes you zone out, and even your own name falls deaf upon your ears, no matter who may be calling your name. But when you hear the soft, yet gruff, "hey, baby?" he knows he has your attention.
Bucky wont call you "doll," it feels foreign on his tongue. He cycled through many different petnames, trying to figure out which felt best out of his mouth, and figuring out which ones he felt suited your face.
But, by far, the one Bucky rarely ever calls you, but his absolute favorite, because it just fits you so well in his mind. Its one he only really uses when he knows you need a verbal reassurance, one he only uses when he knows you've had a rough day, one he knows you melt upon hearing. You'll hear something like; "You okay, Angel?"
And he instantly knows he's won you over.
