Roddy hears Dodger loud and clear even though he's in another room, aided by his rodent hearing. That meant this all fell on him. It also meant that Roddy was on his own, and if he ran into trouble there would be no one on his side to save him. A terrifying thought, but Roddy forced himself to focus on the task ahead of him.

Climbing back out of the drawer column, he went around front and decided to climb up the front, gripping his tiny rodent hands and feet onto the handles to go up. It was now he could see the lock, but part of him hoped it wouldn't be...

He gripped on the handle with both hands, using his feet to push against the drawer below, trying to pull the drawer out. No use. It didn't even budge and it was, Roddy concluded, most likely locked. Scurrying away from the drawers for a moment, Roddy looked for something heavy enough to smash the lock.
