"<b>You know her as:</b> Sister Mary Eunice, the innocent nun turned demonically-possessed monster <br><br> <b>Why we like her:</b> Rabe already impressed as socialite spirit Nora Montgomery on the first ""Horror Story"" miniseries, but she's found an even bigger showcase as Mary Eunice in the second. Originally a sweet counterpoint to Jessica Lange's authoritarian Sister Jude, everything changed when Mary Eunice was possessed by a demon after she witnessed an exorcism. Now she's a sexually assertive terror, protecting the diabolical Dr. Arden (James Cromwell) and psycho killer Dr. Thredson (Zachary Quinto) alike. Few actresses get the chance to demonstrate that kind of range, and do it as well, as Rabe. <br><br> <b>Where else you've seen her:</b> The daughter of late actress Jill Clayburgh and playwright David Rabe, Lily Rabe is best known for her stage work including a Tony-nominated turn as Portia opposite Al Pacino in ""The Merchant of Venice."" But she's also guest starred on ""Nip/Tuck,"" ""Medium,"" ""The Good Wife"" and three different ""Law & Order"" series. <br><br> <i>-- <a href=""http://twitter.com/geoffberkshire"">Geoff Berkshire</a>, <a href=""http://www.zap2it.com"">Zap2it</a></i>"
