What happened to Ismene??

I just finished Antigone, and I'm confused. I understand the end of Antigone, Haemon, Eurydice, and Creon but I do not know what happened to Ismene. Her last line was " Poor Haemon! How your father disgraces your name!"And then she is taken inside, with her sister Antigone. Antigone is later taken out, but is Ismene still stuck in the room where she was take?? Overall Antigone was quite an interesting story. The ending was sad but not as sad as Oedipus! These types of stories are so depressing, but I think that Oedipus, and Antigone were more interesting then I though they'd be. I was really disappointed in the beginning when Mr. Thompson said we would be reading plays, but these plays made me want to finish the story.
