Mikey wasn't sure about Master of Stealth. Or about Spencer's mental health. Because frankly he looked a bit like he was lurking. And lurking with suspicious intent. Intent to do what though, he didn't know. Jump someone and demand all their plants? Meet William for an impassioned elopement? Win a very serious game of hide and seek?
"What are you doing?" he asked frankly, seeing no other way to put it. "I just got stopped on my way to bed by two first years saying they'd seen a robber come to kill everyone in their sleep."
