I've been mulling over this for way too long anon, sorry for taking my time.
Questions like these are always hard because some character traits will only show themselves to me while I write them, or have more time to spend with them, so some of these things are more fluid.
Douglas has a charming personality, he knows how to work people. He can be aggressive but in a heated, temperamentful way. He is fiercely loyal but in comparison to Willow his loyalty lies with people, he's protective but can be very posessive.
Willow has never had the need to be charming or good with people. He is demanding the way spoiled children are. Most of his character is because of his upbringing though, so I know there will be changes when he gets out of his current setting. Willow is also loyal to a fault, to very few people but more to a cause, to an authority. He isn't as bad as he sounds here, I'm just really bad with giving people positive traits XD
Sorry for the rambling, I think I could've written 10k more words about them both though so I think I did a well enough job XD
