Jessica Williams (Kenza) was never credited, but Tati Gabrielle was. I'm fairly certain she played the Grounder that called out Roan from the crowd. As far as who she is (and if the character's name is Gaya or something else), I haven't seen any official information. Unofficially, Grounders Source says the character is named Gaya & she's Indra's daughter. On the other hand, IMDb is saying Tati Gabrielle played Kenza, but IMDb regularly gets these types of things wrong too. Twitter skikru has also previously listed her as playing Kenza. I think we'll have to wait for future episodes to find out for sure who she is.

As for the final scene: Since there was a pyramid, I assume it's Egypt, which means there were Grounders in Egypt. This means Becca's anti-radiation cure wasn't the only cure created or Becca's injection wasn't an anti-radiation cure (and she was just magically immune to radiation) or in 95 years Grounders have spread all the way from Eastern US to Egypt with limited technology. I'm not sure which of these theories is more far-fetched.
