I have a question (or two) about the crack ship about "main character of a book series I read in middle school and only finished out of spite/an OC descendant of a webcomic protagonist that literally came to me in a dream." Is this a ship with Percy Jackson and a descendant of Agatha? Also what's the dynamic between the two?

Percy Jackson I actually read in elementary school and love and adore to this day. Alex Rider is the one I finished out of spite. (I was considering dropping it during... Book 3? I think? And then a boy in my social studies class said "isn't that series for boys?" So I finished the entire thing even though I was bored to tears by the writing style.)

Yes it IS a descendant of Agatha. Her name is Labyrinthia Heterodyne and she did not actually appear in person in the dream so I had to invent her from scratch. She hasn't decided if she's going to be a Bad heterodyne or a Good heterodyne but either way when she grows up she will probably be taking over the entire continent. For now she's content just being Eastern European Kim Possible who causes problems on purpose.

The dynamic is very. Our nations are allies but I don't fully understand you and know your priorities will not fully align with mine but also I trust you to do the right thing. You intrigued me but it wasn't a crush until I realized that you were a mirror in which I could see a part of myself that no one else understands. You're certifiably insane and tbh it's kind of hot.

Question: Who is Labrynthia and her ancestor/ancestress? How did she meet Alex Rider? Why would/did she kidnap him!?

So because they mostly only meet up while Alex is actively doing spy shit, Labyrinthia spends most of their situationship under the impression that Alex is in the same boat she is: i.e. his family is the business (which is correct) and he is doing this out of love for queen and country (sort of correct!) and, crucially, has the option to stop (very incorrect).

When Alex gets shot by that Sniper, instead of just almost dying I think he does die and gets revived by MI6. Labyrinthia finds this out because she goes to steal the body from his grave to try and revive him (#justgirlythings) and finds out it's already empty. This is when she figures out something weird is going on which culminates in her kidnapping Alex back to Mechanicsburg so he can stop being yo-yoed by intelligence agencies who can't decide whether or not they want to keep blackmailing him.
