Beginning
He hasn't tried to get Mirage to cook for him since their very first months together. It's not because he buys into any of that woman as Goddess, above menial tasks garbage, or because he wants to protect her dignity. On the contrary, Mirage is kind of fun when she's all mad over some perceived indignity. And he'd pay a hell of a lot to see her sashaying around in a frilly pink apron.
Especially without other stuff on under it. Whoo-ha!
But he's still recovering from the last time, when he whined and pleaded despite her alarmed protests that she had no desire to poison him yet, until she agreed to make him something simple to keep him quiet. The pangs of indigestion were the stuff of nightmares, and just what it took to make him believe that it could be "that bad".
So, he just doesn't ask her anymore.
