Zagreus is not as comfy as he was a few seconds ago, and Thanatos frowns. It is none of his business if his mother is seeing someone. He should be happy for her finding love. It bothers him more than it has any right to that their mothers were kissing, and he's wondering if he's not as supportive as he hopes or if it's just because the other person in question is Zagreus's reunited mother. And it's making things weird. For them too!

"Has your mother told you anything? Or... has she and my mother kissed again been in each other's company lately?"
