Summary: Sammy was staring up at the mobile, which was spinning. When Mrs. Edwards remembered to wind it up, it would just turn, but this time each mouse was also twirling, its little arms and legs rising and falling, dancing to some unheard music. Sammy cooed and reached out his fat little hands, and Dean stared too.
Then Sammy yawned and turned his head. The mobile fell silent, rocking a little with momentum.
Review: this is a fascinating 'how things would have been different' fic, and it's always nice to find stories focussing on Sam's powers, because they're awesome and frequently ignored. The characterisation is spot on, the ideas fascinating and the writing every bit as good as you'd expect from an author as talented as rivkat.
Sort of maybe kinda dubcon? It's hard to judge. Avoid if that's a big problem for you.
