Bruce & OTA (multiples welcome)
This sort of thing still made Bruce intensely uncomfortable and he was hoping that all went smooth with the extraction of Loki. If anyone could get it done without attracting attention it was Valkyrie and Wanda. The rest of them were simply there as a distraction and potentially a backup plan though he was pretty confident they wouldn't need to provide backup. Mostly confident. Incredibly hopeful. Worst case, he'd let out the Other Guy as the ultimate distraction, but he really did not want it to come to that.
He was nursing a glass of champagne as he kept to the edges of the crowd. Thanks to the Other Guy, he had a high tolerance for alcohol, so he wasn't worried about accidentally drinking too much. The ceremony was beautiful and he was happy for Thor and Jane.
