Oh yes, Door was totally manipulating him! And if Windkin is blind to the flaws in his own character, then he might just feel like he was dumped or betrayed by Door for no good reason? I've not read New Blood for a while, so my memory of what actually happens towards the end is very hazy, sorry. :oops: But yeah, bitterness could definitely lead to lashing out at others (or kicking them in the head )!
Windkin is starting to remind me more and more of Edward in Twilight - all he needs to do now is fall in love with a nice elf girl and tell her that "You're my personal flavour of dreamberries". :roll:
