Step-by-step explanation:
Maryanne's attorney is requesting to strike juror number 13 due to a potential conflict of interest. In legal terms, this is known as a challenge for cause, where a prospective juror is disqualified from serving on a jury due to a specified legal reason. In this case, the reason is the juror's personal relationship with one of the parties, specifically being Trory's first cousin, which may affect her ability to be impartial.
