Oh, sweet Jesus, this is going to be huge!

Dylan's conjugal visit. 

Upon rewatching S02E03, I'm pretty sure I caught something big!

When Ms. Huang comes in at the end of Dylan's 18 minute session with his Outie wife, Gretchen, Dylan and his visitor are making weird mouth movements. It's easy to miss but definitely there. 

Then, when the show cuts to "kind of a fuck-up", Outie Dylan sitting on the couch, Gretchen mentions making cookies and and to "remember Merrick's ear thing". There's some incomprehensible kid mumbling, and when one of the kids (not a wild stab to say it's Merrick) says "bye" to mom, it sure looks to me like Merrick is deaf!

Also! In S01E06 in the closet with Dylan and Milchick, it's Merrick(!) who busts in causing Milchik to angrily blurt "We told you to count to a thousand and wait outside." Of course Merrick didn't do this because he didn't hear anything!

And what conclusion does that bring me to? Gretchen and Dylan can lip read(!!!) and they're having a completely different conversation other than what can be heard by Ms. Huang. Watch that scene again and you'll absolutely see it. 

At the end of their conversation, assuming the lip reading skills, it looks like Dylan asks Gretchen a question to which she seems to respond somewhat reluctantly, "alright".

And now for a little conjecture. I think Gretchen enjoyed being with childlike, not-a-fuck-up, Innie Dylan so much that she wants to either have him reintegrate or swap him for Outie Dylan! Watch the scene back at the Outie house and tell me you don't see it.
