And then the second question escapes Than's lips, and it hits Zagreus somewhere deep down that makes him finally realize the truth of the matter. Thanatos wants him. Thanatos loves him too.

"Than...!" His face spreads into a grin, and his breath comes out in relieved laughter. "Hahaha, oh, you're right!"

Zagreus acts upon this impulse, releasing Thanatos' grip to rest both of his palms along Thanatos' jawline, thumbs brushing his immaculate cheekbones. He leans in, pressing an earnest, open-mouth kissed on the lips he's wanted to kiss for so long, drawing Thanatos into him with a fire that's been burning in him since long before the Train, now given name, now given form.

I love you, Than.
