Chloe's role is necessary to the story. I hate giving spoilers, so I'll say she's OLD, and almost as much a puppet to the voices as anyone else, but she has a hard edge, and will do whatever is necessary to force Owyn to save the day... even if that means getting roasted by a dragon.
As Book 2 and 3 unfold, MC becomes a bit darker toward many outside his inner circle (Knight of the Lake). Even Chloe gets push back.
As for Bella, Droid has shown pics from Book 3 with Bella, and promises a "happy ending"... eventually. Also shows her love for MC, and self sacrifice. Besides, it's a war, and people die in wars.
What I learned from my husband is that any good super hero, or good villain, must have some twisted and often sad back story or weakness. Owyn is a "god", wrapped inside mortal flesh. He can be hurt. Emily is his inner strength, and greatest weakness, as he states more than once that he would gladly break reality to save her.
Just remember, this is a 3 part story. )))
