It's a pretty obvious choice, but that doesn't make it wrong.

Puppy doesn't understand at first. Does Schön not like her anymore? It's only when she turns to her tall one for sympathy that she realizes, oh no, sads! Must defeat the sads! Time for upsies, tall one, so that Puppy can lick away all the sads.

(There may be a reason Verity let herself get talked into this.)

"I've never really thought about it," she admits quietly. Baby names aren't something she's let herself mull over in life. Puppy will have her upsies and a cuddle.
