I felt really sad seeing the classic signs of post-partum depression. Even more sad when Harsen saw all those signs and didnt recognize them, he cant understand why she kept crying, kept on staying in her room and losing all function. He loved her, I get it. He married her despite knowing that he would encounter a lot of hardship if she chose her. All those wars he fought was the price he was paying so he could be with her. After all, that was where he was good at, at fighting. He lacked in areas where he didn't know how to express his emotions well. On the other hand, Ercella was feeling disconnect towards her husband and his people, ended up feeling all by herself, didnt even know what was wrong with her and just wants to be loved in the end. I know she didn't mean to offend Harsen with the "best choice" thing, considering how she grew up in a political family. And all the sudden changes she went through after giving birth and having a son.
They were perfect for each other, but met at a really bad time.
