You've officially made me cry.

This was beautiful. I love the shift in tone, the excited, frantic energy from the beginning, the sheer joy when she finally finds the TARDIS, and the utterly heartbreaking conclusion when it dies. The bouncy mood of the beginning served to make the ending all the more painful. I love how you've made being a Time Lady so important to her, and her voice is absolutely perfect.

Seriously, this was absolutely brilliant. =D
