Kid Alisdair
Youngest we see Alisdair within the main story and the appearance he has at the beginning of The Posse , aside from his current gear , as he gets that in Part 1
I guess the structure of The Posse has changed a bit
The Prologue and Part 1 is where we see this iteration of the character , plucky and pathetic but still strong willed , Part 2A is where we’ll see his teen years , seeing him be far more jaded , violent but also at a standstill with just where his morals will progress too , Part 2B shows him at a young adult point , aka his green armor phase lol

This post isn’t a lore post so u won’t go too deep into it but his own personal story amongst the 12 has to do with a ton of themes of extremisms , moral growth , and his rejection of his father’s wicked values but eventually also seeing the path that lead his father to becoming symbol of good for many and sympathizing a bit just where he came from whilst carving his own path for a better future against the people that satiate their views with violence , etc etc
Blind justice and rage child that doesn’t know how the world works and came to be , jaded nihilistic that thinks brute force will solve issues but comes to realize his actions aren’t doing jack shit , and eventual actual hero that brings change to the world
