Actually, I'm kinda glad that we finally might lose some more key characters. Angel's death didn't touch me at all, simply because he didn't even speak. He could as well just have been dead since the end of chapter 24. With Datu, we hear his pain as he cries out, we hear how the others help and talk to him, hell, we even hear the man digging his own grave.
I will say though, that he probably became one of my favorite characters, I mean, how many people would be able to go through all the things Datu's been, the arena, Boulder, then Irwin, now this... And then even be strong enough to make their own last resting place? That's just wow.
Was going to say "long live", but doesn't seem that likely, so... Hail king Datu, the resourceful!
