A little blond boy who looks on the verge of tears slides open the compartment door.  "Have you seen a toad?"

She shakes her head. "No, not one loose..."

Wibble.  "I just turned my back for a second - but he must have run off - "

Hermione hops to her feet, crisp and businesslike.  "How many compartments have you checked?"

"Just the ones on this car," the boy says.

"We can help you," Harriet says, also getting to her feet.

"...would you?"

Hermione nods firmly.

Nod! "Absolutely."

Shy grin.  "Thanks."

She grins back. "It's no problem."

"Should we stay together to look, or split up?"

Hermione taps her chin pensively.  "If we're just going down the train in a line I don't think there's much point in splitting up...?"

She nods. "That makes sense, yeah."

"All right."  She nods smartly.  "So our first stop's the next car, then."

"Yeah. And we can ask people if they've seen a toad... Someone must've."

"That's a good idea, Harriet."  And she marches off down the train car's corridor, toward the door.

She follows.

No one in the next car has seen Trevor the toad, as it turns out, or the car after that.  No one's up for helping them look, either.

Awwww. That's sad. But looking's not too tiring...

Hermione seems as determined as ever, certainly.  Knock knock.

Laughter from within the compartment subsides, and a red-haired boy slides open the door.  "What's up?"

"We're looking for a lost toad."

The boy glances back at his friends, who look to be sharing between the three of them a pretty decent candy haul.  "Anyone seen a toad?"

The other boys shake their heads.

"No," he says to Harriet, "sorry."

"Okay. We'll keep looking. Thanks." And turn to keep going.

"If you see him, would you let us know?" Hermione says; she's taken to asking this the last few compartments.  "We won't be hard to find, if we're not in the corridor we'll be up in front."
