First of all, I LOVE fiesty Adelin! That girl really knows her own mind and isn't the delicate flower that needs protecting like Keller thought. I know K was doing what he thought was right, especially with Warren's history, but I also completely underestand Adelin's position. She was to be able to make her own decisions (good or bad) when it comes to her mate. I really hope that Warren proves himself worthy of such a good soul. I'm also keeping my fingers crossed for Tilly. She deserves someone too.
Speaking of Tilly, i loved the banter between her and Tobyn. It's wonderful to see the friendship that obviously means so much to both of them. It'll also be fun for K to have an ally when he needs to get Tobyn to loosen up and not take himself so seriously.
Finally... Kellar's guilt. I get why he felt guilty. He's got such a big heart that deliberately hurting or scaring someone wouldn't sit right with him. Tobyn is right though... k did what he had to, and if the first change is as difficult as it sounds then Warren actually got off pretty easy.
