I wouldnt be surprised if this episode introduces Sabrina, as a backdoor pilot to her series. I remember that Barry Allen was introduced in the eight episode of the second season of arrow. Then again in 2015 the crossover betwen arrow and flash (Also the 8 episode) served as Legends of tomorrow's backdoor pilot.
