Author's summary: The rebel becomes the activist. The activist becomes the recluse. The recluse becomes the renegade.
Characters/Pairings: First Doctor/Susan's Grandmother, Susan's Mother, Susan
Warnings: There's the potentially confusing factor of two characters sharing the same name (though it's easily figured out by context.)
Recced because: We don't really know much about the Doctor's life before he stole the TARDIS from Gallifrey. Oh, canon itself gives us the odd off-hand remark about the Doctors youth--the daisiest daisy and Roentgen blocks, such things are theories made of--but there's really not all that much that's concrete. Really, all we know is that Susan must have had parents once and so the Doctor must have once had a child and that child must have once had a mother (or another father.)
In Ten First Times, Alienist does a credible job of filling in the blanks of the Doctor's first few centuries and the life she creates for him feels very true. The prose is simple, spare, and affecting. By the end it's very easy to understand why the Doctor left.
