Glory recently submitted discovery responses to opposing counsel in a lawsuit governed by the Texas Rules of Civil Procedure. Specifically, Glory responded to opposing counsel's Request for Production. The RFP included on request for all internal correspondence and memoranda sent or received by Glory's client concerning the lawsuit. Glory responded to that request by asserting the work product privilege, but she has just realized that she accidentally included a privileged internal memo in the documents she produced with her answers.

What must Glory do in order to preserve her claim of the work product privilege, despite having accidentally disclosed the documents to opposing counsel?
