Proof of Hayley sure cares about Klaus 💖 and Klaus cares of her.
The reason she was more determined about Elijah's life is cause she LOVES ELIJAH ROMANTICALLY. She needs Klaus she said that in 4x03, she said to Marcel in 4x02 and Davina in the last one 4x08 that Hope needs her father! And what Hayley wants for Hope is a normal safe life ❤️ and Klaus want that too. And he needs his brother that's why he was willing to do something he was almost 100% sure he would survive. Whilst Elijah was in danger and wouldn't maybe survive that.
Elijah would do the same. He proved that in 4x08 💖 so these family bonds between Klope, Haylope, Klaylope, Klelijah, Kleyalijah & Haylijah - are the most important ones. Also ofc the way Klaus still loves Marcel and the other way around. And Marcel loving Hope. This is a show about family. I do see Haylijah as more than just romantic love. They're family too in a sense. Cause Hayley is a mikaelson. And Marcel is too. No matter if they aren't by blood and sometimes fight with different members of the big clan, THEY'RE what this show is all about!
It's not about teen drama or love or any love triangles. Sure there might have been but those triangles are more about family not accepting some or fear of replacing the sibling! This show is amazing cause of its values about family. And that's why I love it 😍
