Hello again!
Since I started writing my own story (that is an alternate universe) and needed to know the timeline for all events, I realized a drastic problem with your story. Even with no actual dates for most of the first season, the wikipedia page with the list of Whoniverse episodes/serials by setting tells me that "End of Days" takes place within a week of election day... and "Sound of Drums" and "Last of the Time Lords" happen within a week after election day.
Trust me, it's confusing and timey wimey, but trying to stick to the timeline that RTD created is important. (He's bad at timelines himself, so don't feel bad.)
I really enjoyed "Secrets of Blood." It is a brilliant story, really clever and creative. It's also really sweet, giving us a different look at Jack.
I have this odd longing to see a one-shot about how Jack and Arabella meet up again after forty years. Again, I'm not expecting a huge story, just a one-shot - because I find the idea too fun to resist. I just think it'd be fun.
Also, I think your timeline is screwy when it comes to how Jack died in your story in regards to Ari. I thought it was off to begin with, but I just went and double checked an airplane invention timeline, so I'm pretty sure something's weird with it. See, you say that Ari and Jack meet in 1873. I'd guess they got married not long after that, and well... The Wright brothers were still kids and there wasn't a type of air-plane that worked very well during those years. Even other creations were in practice until after 1896, even though the Wright Brothers had their first one in 1903. So... just consider having Jack die in a different manner for that back story.
There are grammatical and spelling errors in your stories, but not so much that I can't overlook them. Just keep them in mind when you're writing. Especially with your comma usage - there are times where the comma is in the wrong place or I feel there should be one, but there isn't one to be seen.
Because you seem to be generally following canon, except in regards to Ianto being Pirask and it's subsequent effect, I'm a little surprised in the way "Year of Blood" has started. See, from what I could tell in Doctor Who, Saxon/Master sent them to the Himalayas on a wild goose chase. Your version has it be an assassination attempt. It just seems odd, that's all I'm saying. It's a fun way to force Ianto's hand. I'm also interested to see how this being the 'year that never was' will play out in your story.
Good luck!
