I don't think Nik looks unhappy at all, but he does look a bit lost, as in not knowing what the hell's going on next...haha!! Basically all he can do, is follow his new wife, and smile when appropriate.
What else can he do, the only person there, he could speak to with any fluency was the translator, but if you notice, his wife was also filling him in on things too.
All will get much better as his wife learns more and more English and is in an environment where she can put her English to good use, that's when she'll understand the language better too....
All the best to you Nik and your wife, now that you have your wife safely at home with you now....
David....
