They're in bed, the morning after, and Baz wants some water.
"Snow," Baz says, and Simon turns on his stomach, blinks awake, and grins at him, huge and smug. It should be insufferable but it somehow isn't in the least.
"Not Snow," Simon says, still grinning.
Right, Baz remembers. Not Snow.
"Fine then," he says, and opens his mouth to say Grimm, but of course that won't work either because that's his last name, and dammit but Simon looks ridiculously happy.
Baz does his best to glare at him. "This is why you asked me to marry you, isn't it. So that I'll have to call you Simon."
"You figured it out," Simon deadpans, but he's trying not to smile. "My secret plan."
"I'm right, aren't I."
Simon smirks, then rolls over and is asleep again within seconds.
Baz stares for a moment (stares at his husband for a moment).
"Good morning, I guess," he says, "Simon."
