Luckily for Duster - or maybe unluckily - the current resident has pretty good senses for these things, and hears him enter. Besides, Sparks has been through several roommates by now, and has gotten used to the new rotation. It's a fairly small house anyway, so Sparks could hear Duster speak up even from upstairs.

A head pops out from the staircase, giving him a raised eyebrow in appraisal. Looks like a male roommate this time.

"That so, huh. Yer not just a guy wanderin' in here for the heck of it?"
