---------------------------------------------
Things not played out but referenced in the threads:
Graduation - 1/26/2010 - Snape leaves the ship for three months and grieves for Lily and Albus. Much of this time is spent being questioned by Aurors regarding his physical likeness to a dead spy. Returned as a warden 1/28/2010.
Leaving the Ship - 6/21/2010 - Snape leaves the Barge in the wake of his encounter with Martha during the amnesia flood. More of the same from the Aurors; during the final two months, Snape was imprisoned in Azkaban. Returned 9/8/2010.
Two-week holiday in Diagon Alley - February 2011 - Much of it spent incognito or running from the Aurors.
Barge Wedding - 5/23/2011 - Merlin officiates over a secret wedding in the CES.
Post-Mirrorverse Holiday - 8/24/2011-8/27/2011 - Six months spent in New York, London, and the Potterverse. During this time, Snape met Martha's family, reconnected with Molly Weasley, and introduced Martha to his mother (?). During the final month, they had an actual wedding (attended by Jack Harkness, amongst others) and two-week honeymoon. All expenses were paid by the Admiral, because Snape is a dick and kept his port credit cards.
Jack Harkness attends the wedding, from the drabble meme. Written by Ari. (F-locked)
One of their major fights occurred during this trip - Martha's mother insisted they spend the night before their wedding away from one another. Snape took this news badly.
----------------------------------
Post-TLV Errata:
- Snape's deal, for lack of anything better to ask, was to make Martha a witch. Martha's deal was to extend her own life to match his.
- Place of residence post-TLV is a wizarding community near Loch Walton, in Scotland. Their house, found by pure chance (and paid for with one of those credit cards the Admiral hands out, thank you very much), is called 'Bookford Cottage' - though the ornate 'd' looks suspiciously like a 't'. Snape refuses to acknowledge this as anything more than coincidence.
- When Mozenrath joins them around 2015, the Admiral has aged him down to 11. He attends Hogwarts with the Potter children - and is particularly dismal at wand-waving.
"Late-night phone call" from the drabble meme. (F-locked.)
- Children: Angelica and Kay (biological) and Mozenrath (adopted).
'Angie' one-shot. (F-locked.)
- For the purposes of post-TLV PSLs, the Potter and DW worlds co-exist. Explanation: the Doctor lies. When Snape asked the Admiral to allow them a way to move between worlds, the Admiral gave him a map of the tube and told him to mind the gap.
- Snape secretly enjoys the company of the Eleventh Doctor, but misses Ten. Because you never forget your first Doctor.
