After helping Dominic fight the
virus spell, Mia was exhausted.
And in pain. Getting slammed into a wall and having sharp virus teeth grate across your back can do that to a person. Not to mention it left her robe in shreds.
It wasn't long after the battle was over (the battle that used all of her starlights) that Mia learned that the virus had indeed affected her: for now, and who knows how long it would last, her magic was gone.
She's only half-certain about what Draco's going to do when he finds out she can't use her magic and that the cause was a virus spell, the latter being where she's half-uncertain. She fiddles a bit with the ruined robe as she thinks. The more she thinks, the sleepier she gets.
Before Draco comes to their room for the night, the robe is discarded in a corner and she pulls on a modest nightshirt. At least this way, there's some barrier between his hand and her back should he think to hold her. She doesn't know what will happen if he touches her wounds, nor does she think either of them wants to find out. She carefully climbs into her side of the bed, feeling as though she could drift off to sleep at any moment.
But she would like to wait for Draco so that she can kiss her husband goodnight.
