she is not leaving per se. well, kinda but she is not quitting. there was this interview with clevvertv.com which i saw. that says and i quote" i'm not quitting, but in the fourth season there will be a family wizard but i'm not sure about the future of the show." (or something like taht dun, waliopelekwa remember the exact words) she not quitting but the onyesha is most likely to end as they are gonna have the competition and announce a family wizards. and with out the justin, max and alex as wizards they dont really have a show. so they are gonna end it.
