Not sure if anyone else has caught this and written about it already but on my many many many rewatches of the last part of 5x08 this morning, something occurred to me...
The only time Claire and Carmy interact during the birthday party scene, Carmy is largely facing away from the camera towards her:
Facing backwards, facing his past.
Contrast this to him looking at Syd as she cuts the cake:
Facing forwards, facing his future (with a smile on his face). Illustrated excellently in action by this gifset.
I think that's pretty cool.
