In general, when you draw a weakness from your deck, after resolving its effects does it remain in your hand? Does it go in your threat area? Or do you discard it?
For instance, when I draw Paranoia, after discarding all of my resources what do I do with the card? Does it stay in my hand to take up space (because you can't voluntarily discard a weakness)? Does it go in my discard pile to potentially be drawn again should I have to reshuffle? Or does it stay in my threat area to keep it from being drawn a second time (seems unlikely for Arkham Horror)?
Also, with Roland's Cover Up, that goes into my Threat area with clue tokens on it until I successfully remove all of those clue tokens. Once that happens, do I discard the card or does it remain in my threat area?
The rules are bizarrely unclear on this, and that may just be because the answer is so obvious to everyone but me that they didn't think to write it down.
