A Place Called Home, by
sheldrake.
G. Martha.
What's so bloody special about being human, anyway?
Spoilers: Human Nature
On her afternoon off she slips quietly away and lets herself into the TARDIS, so she can sort her hair out and sing in the shower. She sings about how the distal phalanges are connected to the middle phalanges, and the middle phalanges are connected to the proximal phalanges. She is cheerful, capable Martha Jones, who's very nearly a doctor, and who takes everything in her stride. She can name all the bones of the body, and connect them up, and make them live. Dem bones are gonna walk around, oh yes they bloody well are. You'll see.
Beautiful Martha character-piece.
