So I looked through like six pages of the rules forum and couldn't find this asked anywhere.
If I take control of say, The Kindly Man, and he dies, what happens? He says attach to "your" house card as "your" only agenda. It doesn't say attach to "owner's" house card as "the owner's" only agenda, so he would go to the controller's right? I know that whenever a card leaves play it is going to the owner's out of play area by default, but these seem to specify the controllers out of play area, so not sure if that would override the default of owner's out of play area.
