Okay but if we're doing headcanons here for Tythan then just imagine this: Mark is doing some charity livestream and playing games on the couch while the others are "gone" but it turns out that Tyler and Ethan are behind the couch cuddling and kissing off camera, and Mark never realizes that they are, and Amy and Catherine just kinda snort at the oblivious Mark
!!!! I LIVE FOR THIS NOW !!!!
i love how in nearly every ship headcanon, it involves amy and kathryn being the insiders i love it
also bonus points if tythan is behind the couch together because ethan is showing tyler memes and tyler just laughs and puts his arm around ethan so cASUALLY AND AMY AND KATHRYN DO A TYTHAN NUT
