Yup, can see you've already talked Dead Beat with Luce, but I was aiming for John having control of Bob when he held him, which is why he immediately obeyed the command to sleep. And if John had actually understood the power he'd taken and wanted to claim ownership, he probably could, but he doesn't understand and doesn't want to make a claim anyways, as he's invested in respecting Harry's property/feelings.

...Harry would totally freak if he came back and Bob was sat on top of a pile of finance reports :-D
