   Summary

   Riza is dead asleep again by the time that Roy gets her settled in the passenger's seat of his car. It's unusual driving, given that Riza tends to drive him everywhere and every one of his senses is overpowered by his stupid, instinctual brain telling him stupid, instinctual things like 'your omega's in heat, go home and make a den, get her to nest in it, feed her good food, knot her until she feels better, and make her yours, yours, yours'.

   God, he's so fucked.
