@XxRennxX iirc actually if it's like the novel (because some was edited & modified in the manhwa, so a bit different from the novel) then..
Spoiler!
So, when someone from the police dept (something like that) interview Camellius/Camellia then Claude's also beside her and he answers that both two of them was together all night in the Imperial Palace's room on that 'incident night' so, the 'Camellia' that's spot on Louvre isn't really her, so she must be out of the suspected culprit. And somehow it ruins that b*tch stepmother plan (wonders how her face will shows on this scene, LOL) and then due to Claude's answers to the officer, there will be some rumors that Claude is somehow like men, just like the crown prince but Claude doesn't even give a f*** about it, like he knows the truth and it'll prevailed. Hahaha. 😆
