Soph shows up on Tony's doorstep with a bag of gingerbread house ingredients and a big smile. "Hi Jarvis! Where's Tony?" she asks.
"It was some kinda demon flower. It was big and yellow and it smelled like lemon curd and it looked awesome in my hair."
"That is maybe even cuter than you turning our gingerbread house into Gingerbread Jarvis."
"I think," says Soph, "that every time you see a cute thing your potential to appreciate cute things grows, so that every cute thing you see can be the cutest thing you have ever seen."
"Is that a general philosophical statement, or specifically about me and how everything I see is apparently the cutest thing?"
"That is probably true," says Tony. "Or maybe you just have some kind of cuteness multiplying effect."
"Also, it would be a fair way to make up for my supposed magic immunity being fictional." She makes a little gingerbread bed and starts weaving a quilt out of bubblegum strips.
Somehow, he manages to get icing on the end of his nose.
"...How did that even happen," he exclaims, "I am not building this thing with my face!"
And he sticks out his tongue to try to lick the icing off his nose. Needless to say, this plan is doomed to failure.
Tony is giggling pretty hard himself, in between the exceptionally silly faces he makes as he tries to bring his tongue and the icing into contact.
Instead she sticks out a hand, wipes it off with her thumb, and licks it only when it has been successfully transferred. "There you go. Continue to 'not build the house with your face'. I know you're putting up walls with the strength of your eyelids when I'm not looking."
