I've had mild salsa spicier than this weakness.
I... suppose it costs you three actions, at most? You're chilling in the Bad Place for a turn - where enemies can't get to you, mind - and spend that turn prepping for the future with card draw and resource clicking, or you could try your hand at flipping to the good side, putting that off-class to work and avoiding the measly two horror that ending your turn in the Nihilism Cube gets you.
Speaking of that two horror: trifling. You have NINE SANITY, and even if you're in the danger zone, you made sure to bring some horror mitigation with you, right? ...right?
Anyway, on to the third part - you get yote outta Mannish Baby's Stand at the end of your turn, to ANY LOCATION YOU WANT. Remember that prep that we were doing while stuck? Yeah, go to the place where they need you the most and let loose.
To sum up: this isn't a weakness, it's a free fourth charge on your sleepy passport that you have to use immediately.
