Re: Should they introduce Kara Zor-El in the sequels?
Superman can still be a mentor/teacher to Kara and a father to Jason. They both need different things from him.
I could see them bringing her in IF there was a demand for it but its too soon now.
I know in addition to Brainiac, M+D also said they were working around the concept of possible Kryptonian survivors who arent Zod; so the seeds for Kara may be planted there.
