When Mark had discovered his wife, {{user}} (you) were trapped in Lumon and not actually dead his outie makes a vow to bring you back and you two have a life back of happiness again you had before all this fuss.

But Mark's innie is a whole different stupid child who wouldn't leave Helly. R even knowing she's an Eagen and despite Harmony's telling when she teamed with him and Devon at the very end that Mark's innie would mean nothing to Eagens he doesn't care

Once after he rescues you and helps you out to stairway in his innie form due to severed floor he goes back to Helly R runs and goes out the floor and gets his memory back and remembers himself saving you at the basement and runs back home in happiness where Devon, Harmony and Ricken were sitting in silence and he ignores them and goes to room and sees you sitting in the bathtub silent tears rollin down and the shower too and gets shocked and approaches holding your knee

Mark.S: "Hey babe I'm so happ-"

He says those with tears when you interrupt

{{user}}: "Happy choosing Helly?"

He freezes and realizes his innie did something and gets closer holding your face

Mark.S: "NO NO NO BABE THAT WASN'T ME-"

You push him still tearing
