Sounds like Henry is not long for this world.
It is interesting though that he is recognised in the future of TTL as a rival king and numbered accordingly, rather than a mere usurper.
This suggests a future king claiming title from both Henry and Louis against another, possibly only descended from Louis.
Maybe Louis only leaves daughters whose sons fight it out over France and England before dividing between them.
Honestly, the inclusion of Henry as a rival king (being numbered accordingly) is a point I thought a lot about. It seems highly unlikely that the Capetians would choose to ever recognise Henry as the legitimate Henry III and thus refer to any future Henry as Henry IV. Ultimately the view I took was to refer, as part of the timeline, to Henry as Henry III (and so I will refer to any Capetian Henry's as Henry III/IV, Henry V/VI and so on) so as to not show any favouritism and so as to acknowledge that, ITTL, there ARE pro-Plantagenet historians who would undoubtedly refer to Henry as Henry III. Simply put, I did it to retain neutrality in regards to who is king and who is not. This is especially important given that I am trying to deal with both kingdoms fairly and so the kings of both should be recorded. In such a situation, periods such as 1224-1228 in which the Capetians don't actually hold England become difficult.
RiseofBubblez said he was more or less following the great lines of the first version, so without spoiling too much, Henry has another few years to live before ...
Okay so yes, I am following the general lines and gist of the first one so far. That said, there have already been a few major changes in how things have progressed and so the differences between the 2017 and the 2016 timeline (the rewrite and the original respectively) will grow as time goes on. Case in point, in the 2016 timeline Louis wasn't absent from England for long and returned relatively quickly which resulted in his absence when Theobald revolted. In turn, this led to a larger revolt if I recall but also greater difficulties in putting it down as the royalist forces were headed by Blanche of Castile and her supporters. (By the way I'm making an edit to the chapter with Theobald's revolt to give an overview of the conflict which I honestly should have given the first time around).
