Female Bilbo Get Found Out
I’m looking for an au fix where Bilbo is a girl and either Gandalf has her travel as a male, or the dwarves simply don't recognize that she's female. Either way all the dwarves are under the impression she is a he until they reach Bree. Then one of the dwarves, Oin I think, discovers Bilbo's a she while they are in Bree and gets Gloin to help him protect her and her secret.
That’s all I really remember of it.
