Sherlock gets his first call from Bella's father asking for interpretation of a Pokémon the following morning. Charlie is on the line, but a Geodude can be heard muttering to itself in the background.
"So this is Charlie's house. Let's eat something and then go meet him at the station, see if he can direct us to Tiffany's trainer." She shows Sherlock to the kitchen and starts investigating it.
They do! Sherlock can probably tell by the available food, even if he couldn't guess from knowing Bella, that Charlie does not eat particularly inspired meals when his daughter isn't around, and that she is around sometimes but not for long or regularly. Nonetheless, Bella collects pasta fixings. "Not really enough room in here for cooperative cooking, do you want to or shall I?"
"All right." Bella yields the kitchen to him and gets some 'mon food out of a closet; she feeds her critters while Sherlock works on the human nourishment.
The human nourishment, when it arrives, is impeccable. Sherlock takes his turn with the 'mon food after presenting Bella with her pasta.
"This is really good," says Bella, after she has eaten about half of her pasta without pausing long enough to make any remarks about it.
Bella nods, puts the dishes in the sink, and goes out; she rides Branch through the town rather than risk tripping.
Presently they are at the police station, which is circled overhead by a Noctowl; it ignores them. Bella hops off Branch, puts him away, and heads inside.
And there is Charlie. "Bella, hi. Sorry I wasn't home to meet you." He gets up and hugs her.
"It's okay," says Bella. "This is Sherlock, Dad - we were wondering if we could talk to that Geodude? Tiffany?"
"Nice to meet you in person, Sherlock. And I can tell you where the trainer lives; she's in the apartment block by the ice cream place."
"Actually, I do," says Sherlock. "Little-known fact - Ditto can eat paint off of most surfaces. It turns them colours for a little while. Mycroft finds it very entertaining."
"That sounds potentially very awkward for Tiffany, but sure," laughs Bella.
