There are "standards" under both the Family Code and California Rules of Court to govern the duties and responsibilities of professional (paid) monitors, which includes having to observe the child for the entire visit and make a record of such observations. The Uniform Standards of Practice for Providers of Supervised Visitation sets forth the requirements of professional monitors.
If you feel as though the monitor is not doing his/her job properly or is not adequately trained and familiar with the rules governing supervised visits, then you should retain counsel who can assist you in changing the monitor, exposing his/her bias on cross-examination, etc. Under no circumstances should the monitor or parent question the child about the family law case.
The other thing you should consider is whether the child (hardly a child at 13 years old), is sufficiently mature enough to express his/her desires about who he/she wishes to live with etc. Information about the child's preference can be found at Family Code 3042:
"If a child is of sufficient age and capacity to reason so as to form an intelligent preference as to custody or visitation, the court shall consider, and give due weight to, the wishes of the child in making an order granting or modifying custody or visitation...."

The visitation takes place with a primary interest of what is best for the child and keeping him/her safe. The court will examine the circumstances you outlined and may or may not change the monitor, or the method and opportunity for visits.
