Regardless, just as Rei was taken be Gem because the head of the labs should be controlled by the GM, the same should go for the head of engineering. We could shuffle things around to eventually make Alice the head of Engineering, which would involve her secret coming out first since she'd be too afraid to have that much spot light. Or, maybe she's offered it, and it ends up exposing her.
But I think that is something we should worry about after the hiatus. For now, please rest up a bit Gem. We all need you, you know that, and we're all concerned for you. We'll be ready and waiting when you get back.
And it has nothing to do with pushing you out. It is because we rely on you so much now. I know I do. I need happy Gem. Fun Gem. He makes me smile, the way he gets super excited about things and passionate about his writing, it makes everyone around him (metaphorically speaking) excited. So please, do what you can to rest up, and take as little or as much time as you need.
