Yeah, totally. Although, she hasn't become a full tribrid, she was still a powerful Mikaelson witch so seeing her go through her struggles would've been cool.
I love Hope when she's around Landon. They're kinda like a power couple, although Hope holds a lot of the power. Landon, the Pheonix, and Hope Mikaelson, the Tribrid who lost her parents. They're like the odd ones out.
You have your reasons. It's fine. However, I think they try to put Klaus in a bad like in TVD but better light in The Originals. It explains his trauma and reasons for hate/reasons why he'd prefer everyone hate him.
