Alex Nikolaev
Alex was very clearly there! He's so proud of his big brother, which is saying something -- for anyone that might remember his wedding, he and Mikhail were still kind of luke warm thanks to a childhood of father-driven sibling rivalry and now he's Mikhail's best man and it's all just very nice and heart-warming. But he did his best to help out where he could before the wedding, especially with wrangling kids since two of them are his own and all that. During dinner, he definitely gave a speech wherein he jokingly took credit for this union because his wedding was where Mikhail and Lucy met. But he also got a bit choked up by the end, because he's an emotional kind of guy and is just so happy for his brother and new sister-in-law.
Come reception, he would have been doing lots of dancing, especially with his Annie, his girls, sister, and mom. He's a very good dancer, so he likes showing off. ;) But since a lot of the extended family that was there was also his family, he made the rounds and was sure to greet all the distant family or talk Russian with the grandparents.
