   Summary

   Curled up at the back of the closet, against the wall and very unsuccessfully trying to hide himself behind the edge of a box of hazmat suits, is Simon.

   Grace stares. Simon stares back, seemingly frozen. He's sitting on the floor, legs curled up, hand halfway through shielding his face. The lighting isn't great, but his cheeks and eyes shine in a way that clearly show he's been crying. A lot.

   "Oh my gosh," Grace starts, panic lurching into sympathy and quickly joined by shock. "Simon?"

   ***

   Simon has barely age regressed before, and never in front of anyone else. But after the events in the SM-13 and while traveling with Grace & Rocky back to Erid, he needs new ways to heal.
