When Lelia looked up and saw the person she had collided into someone on crutches, all her calm melted away. Even with the reassurances from the person she had run into, she could feel her panic rising.
"Oh no, no, I must have hurt you, you're on crutches, and I probably shifted something and I'm sorry, I should have been looking where I was going and now I've hurt you and-"
She didn't get another word out as she suddenly felt her body stretching itself out, fangs sprouting from her mouth as most of her teeth retracted into her head. She would have screamed, but her vocal chords were already gone, and all she could get out was a gargled hissing sound. Her hair retracted into her skin, which was quickly turning into scales, and she felt her arms and legs disappearing as she further lengthened.
"Oh no, not a snake" she thought, as she finished her transformation into a rather large Mojave Rattlesnake.
