[ haha the integrety of the timeline mattering. josh folds his arms, giving him the once over. ]

Okay, uh... universal ground rules. When you go home, you're going home to the exact moment you left. You won't remember anything about this place. If you die, you're going to get ported back in. Unless you die via cosmic radiation, then uh... then we don't really know what happens.

[ he presses his lips together. ]

And the cosmic radiation is the big problem here. Reality's unravelling, and if you get touched by the broken bits its a big messy game over.
