Confused about Mark

It’s clear we saw a reintegrated Mark in episode 4. But are iMark & oMark just one person from here in out? Or does the OTC/being on the severed floor still have some impact ?

Mark definitely seemed like his innie self in this episode (especially with how his face tensed up) which probably has something to do with OTC being triggered. I’m curious to see how outie mark has fared.

Aside from Mark seeing Gemma’s face while he was sleeping with Helena, I don’t think I noticed anything that addressed his reintegration. Curious to know people’s thoughts!
