I, on the contrary, enjoyed the arena part more than the darts part. Or maybe I'm just biased because there was a pair of twins :-)

Made me think of the following scenario: the pair of twins wins the team fight and then as winners they fight each other. One twin defeats the other, cuts off their head and holds it up as a trophy. The audience cheers and the winner smiles back at the audience proudly. And then, all while keeping holding the trophy up and smiling, with the free hand the winner casually slits their own throat as if it was a tangential gesture not deserving any special attention. Like if it was offhandedly wiping sweat from their forehead.
