You watch with a mixture of horror and relief as the rat who attacked you proceeds to shrink away before your eyes, quickly changing from a serious threat to a little, insignificant infant. Had she not been attacking you you might have been horrified, but under the circumstances you're more happy to be safe than worried about her well-being. Like you she's stark naked, so there's nothing but primitive wooden jewelry that falls limply off her body and onto the ground. The change comes so rapidly that you aren't able to watch her large breasts go flat, or her feminine proportions rapidly shrink into childishness. One minute she has you pinned, the next... her fur is as smooth and clean as yours is and you have to catch her to prevent her from rolling off your belly. You could not say where the instinct comes from, but it comes, and you scoop her deftly into your arms right as she starts to roll. Her eyes are wide with shock and confusion - not adult at all. They're totally innocent, childish, and helpless. The rat who attacked you is gone, and a baby has been left behind in her place.
Not knowing what else to do, you sit up, holding the baby against your chest as anyone would hold a baby. The whole room is staring at you, in horror and amazement and shock and everything in-between. Saul is the first to speak, though, dropping down to his knees so that he can get a good look at what happened. "What did you do to Kelly, Day?" He asked, not peremptory, but worried. Could you really blame him? Even if she had attacked you, he obviously cared about this female, which you understood to be one of perhaps many of his mates. Was it really a surprise to you that he genuinely cared for her just as he had cared for you? "I was going to get her off of you! She was just defending her territory! It's a natural reaction to having a strange new female come in with my scent all over her..." He looked a little scared as he looked at you, which hurt you more than Kelly had.
You look back indignantly, but something in you feels... dulled, softened by this little baby. You can't tell why, until you look down. She's not just a baby - Kelly has changed into a mouse. Her fur is white like yours, that's why she's so soft! And her eyes... they're just like yours, not black like they had been! Her tail's soft and pink and... she's yours! But how is that even possible? "I didn't... it just... happened." You squeak, rocking back and forth to shush the little mouse, who had began to fuss as she sensed all the attention.
"Change her back!" Saul protests, not firmly, but clearly not a mere request. "Whatever you did... undo it."
Could you do that? You remember that feeling that filled you when you got attacked. You could probably make /something/ happen. But will you? Making up your mind, you look up to Saul and tell him...
