Alex spent most of the week distracting himself by writing exactly what he wanted to say in all of his officiating and it was actually pretty good, if he does say so himself. He very much waxed poetically before he got to the meat of ceremony and probably got a bit emotional at one point. It was bound to happen. But, yes. He did the thing and was still pretty honored about the whole thing. At the house, he'd have helped wherever he could with bringing out food and making himself useful as needed before eating and enjoying himself. He probably stuck near to Annie a lot, though made an effort to carry his nephew around some to give Mikhail and Lucy a break.
Cassia was really happy to be there at all and people could probably tell. I'd say she probably stayed close to Jillian, but she gave Denver a big hug at some point. Same with Bash! She's not a hugger on most occassions, but this calls for them.
Elias would have sat by his sister during his ceremony, since Alex was otherwise engaged. I mean, he would have regardless, but y'know. He's only known Denver and Bash a short while, but he loves a wedding and would have been all smiles.
Evan isn't a crier, but she very almost did when she walked Denver down the aisle. She gave her sister a huge hug, then did the same for Bash before sitting with Cash. She actually did cry a bit at the end of the ceremony, but she didn't really notice because it was obvious happy tears. At the house, she stayed near Cash and kind of kept an eye out to make sure things continued smoothly. :3
Lucy was very excited for an excuse to leave the house and get dressed up. ;) She would have brought Yuri, though, since she's really not ready for babysitters yet, but he was probably dressed adorably. If he got even a little fussy, she'd have ducked out or let Mikhail do so if he grabbed him first. But yeah! She would have given her congrats to Denver and Bash, as well as some hugs.
Nick was pretty overjoyed to see Denver so happy and it showed. He definitely cheered and clapped when the ceremony ended. He'd have also made Oceana dance with him some, because this is Nick and that's how he rolls.
