It would be fun, definitely, to see Fin among his family. He'd met both sisters, at least, Viktor knew, given one played professional Quidditch for the Vultures and the other was a model who loved to attend Quidditch events. But he wasn't sure if he'd met either of his brothers or any of the cousins. And there were a lot of cousins. Fin was practically a brother in his own way, anyway; not a brother, but closer to Viktor than any of his younger siblings were.
Viktor blinked and then he smiled broadly, positively beaming back at Finbar. "Oh my gods! Congratulations, Fin! I am so happy for you both!" Because this was obviously a very good thing. He knew Fin would be an excellent father. "Now I can return the favor with the babysitting!" He winked.
