Now compare how she was here with the 2011 BAFTA awards when Dan didn’t attend and she was with Rupert instead. She hardly smiled and seemed very bored, even depressed (and it’s not just Dan & Emma fans that have noted that by the way). And she hardly spent any time talking to Rupert, and didn’t sit beside him or stand beside him in pictures (despite not having seen him for months).
From these gifs you can clearly see that Dan & Emma look to each other for affirmation. Especially Emma, she’s always turning her head towards Dan to see that he concurs with what she’s saying. And you can tell that she appreciates the fact that he’s a gentleman. XD
