Summary: A gift for trialia who asked for a Elizabeth/John story, with the prompt "Elizabeth and a girlcrush". Honey, I have no idea how a "girlcrush" is supposed to differ from a regular crush, unless you meant a crush on a girl which I figured you didn't, as you'd requested a het pairing. So I hope this comes close to what you wanted.
