"So, are you saying... Ellena and Thessalis planned this?" Gewen finally found his voice. "What for??"
Mars didn't reply and let Gewen figure things out for himself. He didn't want to accuse Ellena openly because no matter what, she was his friend and they grew up together.
He wanted to be completely sure about what happened, and he didn't actually direct his suspicions to Ellena because of his personal bias.
Without clear evidence, Mars wouldn't want to punish Emmelyn for murder, and he would do the same for Ellena. As the king, he had to be fair and uphold justice.
Gewen was not dumb when it came to woman's heart. He could slowly see what the king was seeing. He knew Ellena well and he liked her because she was his friend.
However, if he wanted to be honest with himself... Ellena would be able to do something like this if she put her mind into it.
