Draco isn’t a fan of pet names but he will sometimes call Hermione ‘darling,’ especially when he’s distracted.

She’ll come home from work and lay on the couch with her head on his lap and Draco will look away from his book to kiss her and ask, “How was your day, darling?”

He normally calls her ‘Granger’, which in itself can be a term of endearment. It’s all in the way he says it:

With fondness, when he teases. “You alive under that pile of books, Granger?”

With a smirk, when he flirts. “Shut up and kiss me, Granger.”

Depending on his tone, it can also be used when he’s angry.

It can be a snarled, “This is who I am, either take me or leave me, Granger,” when he’s frustrated, and a “Just leave bloody well enough alone, Granger,” when she pushes him too far.

He calls her Hermione when it’s serious, when she’s hurting, when he wants to reassure her.

She’ll wake up crying from a nightmare — a remnant of the war he also suffers from — and he’ll wipe her tears with his thumb and whisper, “You’re safe, Hermione. I’m here.”

He calls her ‘swot’ affectionately when she argues with him and insists she’s right. She’s a stubborn one, his wife (but then again, so is he), so an argument can last for days.

“Done being a swot?” He asks in the morning. She’ll snort and ignore it, but still kiss him before leaving.
