*a few months after the breakup*
          
          Snap: *talking to one of his new ghost friends, a guy named Riley* See you around. *Joins Four*
          
          Four: *grins at him*
          
          Snap: What...? Why are you grinning?
          
          Four: I ship it!
          
          Snap: *blushes* Wait, wh-what?! I don't like Riley like that! We're just friends!
          
          Four: Oooh boy, now I have something to tease YOU about! Revenge time!
          
          Snap: Ugh, no, please don't....
          
          
          
          Yep, Snap is bi. Four is too, technically, because that's how canon Alphys is (and he has canon Alphys' personality so)

"To Frisk..." Four read the letter out loud, proofreading it before he sent it. "I wanted to discuss something with you, but I didn't want to say it in person. Too awkward. Our fight a few weeks ago got me thinking... I really do just need some space, if that's okay with you. Okay, scratch that. I want to break up. I know it's disappointing, but... I just need to find myself. On my own. Please understand. Sincerely, Geeky."
          
          Four sighed, folding the letter into an envelope. He set it on his desk, then placed his blue hoodie over it. Four packed a few items into a backpack and said, "C'mon, Arson." Then he, Snap, and Arson exited the lab, teleporting with Four's ring.

Hey TQ, I just realized that both Reve and Damien call Four "crybaby"... but they mean it in slightly different ways. Damien is genuinely trying to hurt Four's feelings, but Reve is just teasing him as she usually does, while still caring about him.
          
          (I added Melanie Martinez's song "Crybaby" to the playlist in recognition of that XD)
