Went back over it with it and it really doesn't feel like it to me, though I can see how you can see it like that. But there wasn't the traditional contest tournament. Instead it's Hippolyta scaring off some would be claimants by making them think they're playing Russian roulette with Medusa's head, and Nubia is the only one around to get the whole "I want you to be queen, while I go off and be Wonder Woman" surprise. And Nubia doesn't actually seem to feel cheated by the situation. It's quite a bit different than it was made to sound in the rumors.
Anyway the random Amazon street brawl was what struck me as more out of place.
