Florida Rules of Criminal Procedure 3.220 Discovery
(a) Notice of Discovery. After the filing of the charging document, a defendant may elect to participate in the discovery process provided by these rules, including the taking of discovery depositions, by filing with the court and serving on the prosecuting attorney a “Notice of Discovery” which shall bind both the prosecution and defendant to all discovery procedures contained in these rules. Participation by a defendant in the discovery process, including the taking of any deposition by a defendant or the filing of a public records request under chapter 119, Florida Statutes for law enforcement records relating to the defendant’s pending prosecution, which are nonexempt as a result of a codefendant’s participation in discovery, shall be an election to participate in discovery and triggers a reciprocal discovery obligation for the defendant. If any defendant knowingly or purposely shares in discovery obtained by a codefendant, the defendant shall be deemed to have elected to participate in discovery....
(h) Discovery Depositions.
(1) Generally. At any time after the filing of the charging document any party may take the
deposition upon oral examination of any person authorized by this rule. A party taking a deposition shall give reasonable written notice to each other party and shall make a good faith effort to coordinate the date, time, and location of the deposition to accommodate the schedules of other parties and the witness to be deposed. The notice shall state the time and the location where the deposition is to be taken, the name of each person to be examined, and a certificate of counsel that a good faith effort was made to coordinate the deposition schedule. After notice to the parties the court may, for good cause shown, extend or shorten the time and may change the location of the deposition. Except as provided herein, the procedure for taking the deposition, including the scope of the examination, and the issuance of a subpoena (except a subpoena duces tecum) for deposition by an attorney of record in the action, shall be the same as that provided in the Florida Rules of Civil Procedure. Any deposition taken pursuant to this rule may be used by any party for the purpose of contradicting or impeaching the testimony of the deponent as a witness. The trial court or the clerk of the court may, upon application, issue subpoenas for the persons whose depositions are to be taken. In any case, including multiple defendants or consolidated cases, no person shall be deposed more than once except by consent of the parties or by order of the court issued on good cause shown. A witness who refuses to obey a duly served subpoena may be adjudged in contempt of the court from which the subpoena issued.

IMO, Because the depo rules in Florida, Ron cannot take a plea deal that involves agreeing to testify against Misty or Tommy. Although I could believe the DA trying to negotiate a plea deal for this reason, to get Ron under oath in a deposition.
