So, in the "Hades" video game (very light spoilers for Elysium) you play as the son of Hades, Zagreus, trying to escape the Underworld. There are different levels and the boss of the Elysium level (the afterlife for heroes) is Theseus PLUS the Minotaur. Apparently, Theseus found the Minotaur in the afterlife and Asterius (the Bull of Minos) now credits Theseus with "saving" him as a person in death. They're best friends forever now and it's kind of cute.
Zagreus receives "boons" from various Olympian gods on his escapes (it is expected that you die MANY times over in this game, it's built into the story) from the Underworld. There is a boon from Aphrodite called "Aphrodite's Aid" which inflicts "Charm" on your enemies, which briefly compels your enemies to fight for you.
I had this boon in the fight against Theseus and Asterius, and the "Charm" heart ended up hitting Theseus. I usually take Asterius down first, so the "Bull of Minos" had really low health. Theseus stabbed Asterius in the back with his spear and this ended up being the DEATH BLOW.
I felt SO BAD. It is the only time so far that I have felt sorry for my actions playing this game, like, "SORRY, BRO, I DIDN'T MEAN TO MAKE YOU KILL YOUR FRIEND AND PROBABLY REIGNITE OLD TRAUMA FOR THE BOTH OF YOU. IT'S IRONIC, REALLY, BUT MY BAD, MAN. MY BAD."
