Being a huge fan of Shoujo Ai/Yuri, Vastra's and Jenny's relationship intrigues me greatly.
the first time i remember seeing Vastra and Jenny was in the episode A Good Man Goes to War when The 11th Doctor (Matt Smith) gathers allies and storms Demon's Run to rescue Amy and her baby Melody.
As the series progressed it's revealed that Vastra and Jenny are practically lovers so ideally i would have loved to know how all of that started (sure, Vastra's "a lizard" but love knows no barriers)
from what i understand, Vastra met the Doctor some time where Vastra was murdering innocents in revenge of her slain sister before the Doctor stopped her, saving her and occurring a debt to him.
at first i thought her to be Restac and her sister being Alaya, both from the episodes The Hungry Earth and Cold Blood but then i remembered that those episodes weren't set before Victoria London, so unless Restac time traveled (via the cracks in reality?) she couldn't be Vastra under a different name
Now i was pretty sure i saw every episode involving Matt Smith's Doctor and i can't get any publications easily so i am wondering, how/when did Vastra and Jenny meet/fall in love?
