Literally never seen or read percy Jackson and I don't plan to BUT we all know Medusas story right she was super cool and amazing and then posideon was a dickhead and no she has snakes now hear me out Medusa has a kid with a blind person (can't see can't turn into stone) duh right and then that kid goes and falls in love with fucking Percy oh the angst
thinking about how maybe, MAYBE, mok was letting himself be soft and flirty with day despite knowing he was about to set him up with his crush bc he wanted to experience it at least a little bit. he wanted to live in that "we're going on a date" bubble for just a little while before he was to step away.
and then when he did, he realized that even though he did the "good thing", didn't follow his heart but went with what he thought day would want, his heart was still aching. maybe even more so bc now, he knew what could have been.
