⛈️ for a sadness headcanon
Alekto isn't overly familiar with sadness it isn't within their remit. That being said, the schism that broke apart the three sisters (arguably their fault), has weighed on them more than they'd care to admit. It isn't strictly grief, Meg and Tisi are still alive, but they felt a loneliness when they descended that couldn't be filled, no matter how many assholes they punched in the nose. Except there's no turning back now. The damage has been done, Alekto would rather seethe and embroil themselves in trouble then turn back to them both. They'll have to be dragged back to Tartarus screaming.
🌼 for a happiness headcanon
They're happiest when hunting. Albeit in this descension it has manifested in an urge (and desire) to go brawling. There's nothing that brings Alekto joy more than beating the shit out of anyone no reason required. Their closest allies, friends, lovers aren't strangers to fighting. Pan, Brynhildr, Perun, and even those that teeter on the edge of respect and hate like Tez have all indulged Alekto's tastes for violence. Out of all of those that only person that has seen Alekto reach joy (without blood) would be Bryn.
