John Egbert is like…the sburb equivalent of that kid who plays Skyrim but does nothing but mess around for like 50 levels and figure out console commands, then by the time he gets to the actual Alduin fight it takes him like 4 hits to beat it and it’s super anticlimactic. Hence, the HS ending.
Eridan was adamant in his decision that the two of them dress up for a “magical mornin’”, and Sollux knew that any attempt at getting out of it was futile. Despite being utterly convinced that magic is fake, ED still had a soft spot for it, Sol had noticed. But when ED started rummaging through his boxes Sol put his foot down - he could have accepted a cape, but he would never wear that stupid hat and wave a wand around. Not happening, ever. After some arguing ED agreed to let Sol choose his own costume, as long as it had to do with magic. It didn’t take long for the gemini to figure out something to wear. After all, he was a mage, dressing like one from his favourite game was a no-brainer!
