[ Vanitas is learning so much. He wants things like why Aether and his sister travel in the first place - and what a time to wake up on a foreign planet. Teyvat seems peaceful now, but little things sort of told him that there was more to it than it seemed at a first glance. He's glad to know he was right about that.

Vanitas turns pink when Aether leans into him. He's tired, and all he wants is to be reunited with his sister. Like Vanitas, Aether has a goal that sounds simple on paper, but the steps are extremely complex and a journey in itself. It is also something of a relief to know that said goal is not noble for either of them. If it were, Aether would have felt far more out of reach for Vanitas.

Vanitas turns inward to face him more, inviting him to come closer if he needs it. ]

The reason behind you and Lumine being separated is still a mystery, one that I am quite admittedly intrigued by.

[ He says it with a tinge of fondness, implying that he'd like to help Aether, even if information is hard to come by. ]

However, I know that my knowledge of this world is next to nothing compared to how much you know. Therefore, should there be a way that I can assist, I - [ He's blushing again, oops. ] I hope that you'll let me know.
