Cheating is bad and all, but if you really need to talk to her, you might be able to use CoCEd to regain access. The flags "BEE_GIRL_STATUS", "BEE_GIRL_WINS_WITH_RAPE", "BEE_GIRL_WINS_WITHOUT_RAPE", "BEE_GIRL_COMBAT_LOSSES could likely be set to 1, 0, 0, and 0 respectively to unlock the talk option again. No guarantees, as I haven't tested it recently, but it /should/ work.
I'll test it later today.
EDIT: Confirmed for CoC revamp mod. Probably works for vanilla.
