The girl who approached the door had red eyes and a bob of very dark hair. She eyed the gun warily but undid the lock anyway - the City had become a rough place recently and he wasn't brandishing the weapon as a threat. Also, well - what good would a few inches of glass do against a bullet? Not enough good to protect her or the people inside, certainly.
"Please. Come in."
Raven shuffled back to allow Arthur entrance. "I'm sorry about the lock, but the door opens with a push and some of the animals are smart enough to try it." A lot of them were, in fact. The intelligence of some of the beasts was genuinely frightening.
She continued to watch the gun in a series of short, wary glances, her eyes going from Arthur's face to the weapon and back again.
