The Doctor had heard about Cupid Flies time after time on Gallifrey, but never expected to see one in person, much less get bitten by one. The bug makes its victim fall completely in love with whatever other being it sees, and for the Doctor, this being just so happens to be Rose Marion Tyler. Will Rose be able to find a cure while resisting a Time Lord throwing himself at her?

Sherlock is back home after dismantling Moriarty's web and he finally takes notice of his pathologist. *We know that this has been done before but hopefully this will be a fun addition to this couple.* It's T just in case. Now AU due to Season Three
