"Hey, Kit? Are you home? I- I did some talking with Belle, and I don't care what Shadow said, I want to talk to you."
The fox had done quite a bit of digging to find their apartment, from reading through sightings of the two to talking with a few landlords in the area. Client privacy was an easy thing to persuade others to give up when you were THE Miles Tails Prower. It took maybe a half hour to get the address and the keys to the room, not that he'd use them, he didn't want to just waltz in.
When no answer came, he knocked a little harder, thinking maybe the kit just didn't hear him.
He received no further answer. Would receive no answer. As far as the twin-tailed fox could tell, the door looked intact, but if he looked closely at the frame, he'd be able to make out cracks in the paint work where the hinges had been forced past the limits of their anchors. At the his feet lay a damp, darkened patch in the floorboards leading under the apartment's door.
The kit could ask one of the neighbors for a spare key, but most of the other tenants wisely kept their distance from the irate tenrec back when she and her sidekick first moved in, so they would be of no assistance in this matter. All the help he could expect was from a kindly packrat two doors down who seemed to be on good terms with the older cyborg, but even she would be oblivious to the comings and goings of the younger fennec.
