Mary gets up as Jonathan sleeps. She knows better than to have dominating ideals. Knowing the human vial was lost, and afraid she'd never find it in time, she grabs the lizard vial from where it was left, and pours the whole thing into her "mate's" sleeping maw. "You can have your ideass of a lizard empire, I don't want that to happen. You can live life a lizard like your petss... Hmmm..."
With that, she waited until the sleeping Jonathan became a much smaller-than-her monitor lizard (still a larger lizard though), then clothed herself in a heavy robe and hat. She picked up the still sleeping lizard and carried him outside, making her way to his house. The accident scene had cleared, and while people were still wondering what happened to her tree, nobody noticed the heavily cloaked person leave the house.
Once in his house, she placed him inside one of the cages with his larger lizards. "You'll be happy in here I'm sssure. I'll take care of you and your lizardss now."
