Anastasiia Metelkina and Luka Berulava won silver in the Pairs Skating competition, becoming the first athletes in Georgia's history to medal at the winter Olympics. The final event, however, is always the Exhibition Gala, where the skaters just get to show off and have fun, which is when the pair dressed as Sub-Zero and Kitana.
NBC didn't air that portion of the event, but the duo have performed the routine before, at the 2025 International Skating Union World Championships:
If you'd like to see the actual Olympic version, someone on Reddit has helpfully uploaded it until NBC gets their act together.
Berulava was back out on the ice in his Sub-Zero costume later in the gala as well, to help Kazakhstan's gold medalist Mikhail Shaidorov with his routine: Shaidorov was Po the panda, fighting off Sub-Zero and Deadpool.

Wait, they did a fatality but nobody actually died?
Okay, that's par for the course for Mortal Kombat.
