Characters: Martha, The Doctor, Jack.
Ships: Not central, but Martha/Jack, some Martha/Doctor, and a liberal helping of Doctor/Rose throughout.
Spoilers: All of Doctor Who and Torchwood to date, just to be safe.
Summary: There are moments when Martha feels rather like a third wheel, despite the fact that they travel as two.
Author's Note: Although this has tones of Doctor/Rose, it is not in any way a Martha-bashing fic, and it does not bring Rose back. The idea of Martha's reaction to the leftovers of Doctor/Rose was just too intreguing for me to miss. Thanks to liljames for the wonderful beta.
