What happens to Ismene at the end of Antigone?

Ismene, Antigone's sister, appears in two key scenes in
the play. In the play's beginning, Ismene refuses to help Antigone bury their brother
Polyneices. This causes Antigone to break with her sister; she tells Ismene, "I shall be
hating you soon." Ismene appears later, in Scene 2, and attempts to share Antigone's
blame, and therefore her fate, death at Creon's hands. Antigone denies that Ismene
played any part in burying Polyneices, but Creon condemns her, also. The scene ends with
Creon sending both Antigone and Ismene away under
guard.

Ismene is not seen again, but she is mentioned once.
At the end of Scene 3, following his confrontation with Haimon, Creon says that Haimon
"shall not save these girls from death." When Choragos asks if Creon has sentenced both
Antigone and Ismene to death, Creon replies:

No, you are right.

I
will not kill the one whose hands are
clean.

Ismene's life is
spared; Antigone is soon entombed to die. What becomes of Ismene after that is not
addressed, but she surely could not have lived in peace. As she said to Creon when she
explained why she was choosing to die with Antigone, "But how could I go on living
without her?"
