Oddly enough, and after working through Wardrobe Week, this short video demonstrates another important fact: Shane and Oliver fight in multiple layers, and always outside the DLO. Take another look:
They do a good job of maintaining their game faces in front of each other, but the minute they disengage, the toll their interactions with each other have taken in these instances show almost immediately on their faces.
Location is equally important. Notice they never fight in front of Rita and Norman, and never fight in the DLO. It's like they don't fight in the house and never in front of "the kids." Sure, they bring the awkwardness back to the DLO with them sometimes, but they never hash things out there. The Dead Letter Office is where their hearts reside, and most of what they say in those arguments aren't truly what's on their hearts.
Notice also that the moments of forgiveness happen when they're on neutral ground, after finding a way to reconcile a couple back to each other. The first time it was at Ellie and Bobby's wedding, the second immediately after Caitlyn and Joey hashed out the misconceptions surrounding those divorce papers. Forgiveness is what Shane and Oliver do, period. And they often do so without their coats on---and always inside.
I just have to know: Do you think Martha knows just how much subtext she's crammed into this series?! It's unreal!
