The Joker is awfully domestic, in his way. He makes pretty clothes. Nathan's perfectly happy to be a clothes horse for his sartorially-inclined mate. Some of the clothes are distinctly feminine, and Nathan does not wear those, although the Joker could probably talk him into a kilt, even if that's not a Manx thing but only their neighbors.
"I feel like taking the munchkin out for another walk," the Joker decides. "Whatcha think?"
Nate leads them on a different route through Jaipur, and Kerron continues to babble and wave at everyone they pass close to, and everyone continues to find him adorable.
"I love you, munchkin," the Joker murmurs when they get back, and he kisses the top of Kerron's head.
"Maybe he's run through all the phonemes he's heard so far and now he's trying his hand at imitation," speculates Nathan.
But the next thing Kerron says is "Ludigamifrax!", which sounds nothing like anything that has been said recently.
Kerron manages to go without meeting Addy until he is two weeks old, walking and uttering simple sentences.
The instant he sees her, he runs up to her and hugs her leg, beaming up at her.
"Oh, wow," exclaims Addy. "Aren't you a tasty little combo platter?"
"...Excuse me?" says Nathan.
"He's a twofer! He's an ingot and a witch!" cries Addy, picking up a giggling Kerron.
"I'm helpful!" Kerron beams.
"What's my magic taste like?" Kerron asks winningly.
"Pineapple and coconut," she tells him. "The pineapple is the ingot part."
"Mummy can I try those tastes?" Kerron asks, looking away from Addy and at the Joker.
"Sure," he says, and snaps his fingers, and there is a glass of thick, pale yellow juice in his other hand. "Or did you mean separately?" And he steps up and does the pulling-a-quarter-out-of-your-ear trick, except that instead of any kind of coin, he extracts from thin air a divided plastic bowl with slices of pineapple in one half and chunks of coconut in the other.
"God but do I ever love you," Nathan tells his mate.
"I'm tasty," he announces. "Not as good as bubbly though."
"Y'know," he says musingly, "I wonder if that stuff tastes so great in comparison because it's that much better, or 'cause being a half-vampire makes other stuff that much worse. Does anybody know?"
