Pretty sure you're joking about the name "Zende" (hence the lol), but remember, he was born in Africa (they don't tell us which country, lol) and Zende is the name of a village in the Congo Republic. Sasha, is just Sasha, I guess. I don't think it's too strange. There are plenty of "old-fashioned" names on the show: Ivy, Wyatt, Bill, etc.
