Great chapter, nice to see some of the alternate human history. I hope there will be more of these flashbacks of sort in the future, hinting at Susan’s purpose in greater detail. Also, her antice really made me laugh, reminded me of Number 5. I have to wonder though, why was Celestia keeping the alleged weapon of mass destruction in her room, guarded only by her magic that could be easily cancelled? That just seems dangerous, especially given there are safer vaults in the Castle. And also, if Celestia’s only problem was just the countdown, why didn’t Twilight and Luna try to talk to her about it? Or, alternatively, why didn’t Luna at least help them steal Susan by making Celestia fall into deep sleep or something?

Sadly, I actually don't have an answer for these particular questions. While there WILL be more flashbacks, as that's part of the story, I can't really explain simple stupidity, especially when it's on my part. I'm only human. I wish I could think of everything, though. Would make things a lot easier. As for Luna, I was going to explain later in the story where she says she doesn't want to ruin her relationship with Celestia. Although, I could go off the fact that Twilight is Celestia's prodigy. It would make sense if she had SOME sense of how to get around Celestia's bubble. Most other unicorns would most likely not be able to cancel it out.

EDIT: also, here's an upvote for your questions!

Nice looking forward to more
