Kelly was, well. Bored. Almost as soon as Wren was out of sight, vanishing into the belly of the house, quietly enough that even his ears couldn't track her past the first couple of steps. Minus a mental note to keep a closer eye on her for later because while he knew she could sneak up on him pretty easily, it was still uncomfortable to see the evidence of that skill. He may have been a predator, but he hadn't fooled himself into thinking he was any higher on the foodchain than he actually was.
Either way though, with Wren out of sight, the only thing to pay attention to was the house - and the occasional shuffle of someone farther into the house that he kept an ear on halfheartedly. In the dark, at his current height, everything took on an even starker, blander look than his previous impression. Not a whole lot to look at, leaving him to huff silently and curl up. He wouldn't actually fall asleep - lackadaisical he could sometimes be, but he wasn't stupid, and losing attention in a situation like this was the epitome of stupid - but pressed back into the corner, listening to his own breathing, the shallow echoes of life around the house, and keeping his attention perked for Wren, was, in some way, restful. For maybe the next ten minutes.
Small blessing then, that Wren was back before then. He had absolutely no clue what her hands were doing - it was a purposeful movement, something habitual and easy for her, but completely foreign to him - but she wasn't rushing and she didn't look panicked as she headed for the door. So, even if he didn't get the exact message, it was clear they were done and they were leaving. He ran after her, weaving through her feet again, more to make sure she knew where he was, before running ahead and back through the door, ducking into a roll and shifting, springing to his two feet again with a huff. "All clear captain?" he asked with a grin, voice still low and quiet, but unable to hide a bit of enthusiasm.
