Good news if like us you love Isabel's interaction with Felicity, Oliver and Moira. Arrow's executive producer Marc Guggenheim revealed in an interview with TV Guide that Summer Glau will be back as Isabel Rochev in the second half of the second season and that we will learn more about her backstory.
Summer Glau said in an interview that Arrow producers called her for three episodes and that she finally filmed five. Since we already saw Isabel in four episodes (1, 4, 6, 8), we might see her in one more episode only (unless Summer Glau filmed more episodes in between).
Arrow returns Wednesday at 8/7c on The CW.
