Star hadn't been entirely sure what a police box was, but figured she'd know it when she saw it if it was blue and about where Romana said it would be. She wasn't wrong, the thing had been easy to spot. She had her wrench, which was quickly becoming a sort of combination talisman and security blanket, and a small toolkit that she'd been working on gathering since her arrival.
She blinked as she stepped inside, one brow arching, leaning back out the door, just to verify that she'd seen, that the thing really was smaller on the outside.
She verified this twice, before shrugging and padding inside, whistling a 'yoo-hoo' of greeting.
