I’m thinking it’s the paint scene? We had the promo shot of her where her hair is clearly tucked behind her ear… but during the paint scene it was oddly covering just the top of her. BUH! I hope we find out.
I’m going to have to go dig through my archives and find the Emmys nod article where they talk about it. I’m thinking it’s the scene before O’Brien shows up. Timing would work because I do remember Brendan saying he was having a smoke with Siobhan when they heard.
