peat pellet under that? it can wick extra water, if so. prop it up with a toothpick or something -- gently. if dry, water, if wet let it dry on top first. repeat.. it's in corner, so i doubt it's the intensity of light. That can potentially make a seedling wilt too, but typically it's because it is too damp this early.

Did the shell pop off the sprout completely? Otherwise heat stress will cause that lethargic look
