Question about participants in home evaluation...

[Cookiemomma4]

As mentioned in a previous post, we have a court ordered home evaluation.  We are in PA and Pro Se.  The evaluation is being done by Children and Youth and I don't understand the setup, but I guess we will figure that one out later today as we are hoping the evaluator shows this time.
The evaluator is meeting with each party one time for about 2-4 hours.  We were told that everyone that lives in the household including the child in question needed to be present for the full length of time that she is in our homes.  
The other party has someone "just hanging out with them" as they have trained the child to say.  He sleeps on the couch every night and is the nephew of the new mate.  He is also the fiancee of the director of the childcare center/ private kindergarten that they are sending the child too.  There have been some rumors of this person being associated with some drug use so obviously this situation is a concern to us.
Their in home evaluation was on Monday, and we understand that he was not present.  We have come to this understanding through our discussion with the evaluator last night who mentioned meeting "everyone in their home."

1.  Is there a proper way to bring this up?  Should it be brought up to the evaluator or the judge when we go to court?

2.  Would this invalidate any part of their evaluation?  Or is there something else that this could effect?

Thanks for your imput on the matter.  This situation does not seem to be listed anywhere to find out what to do.

Ask the evaluator if he/she met ____, and if not, then tell the evaluator, that if he/she didn't meet ____, then he/she missed an important person who lives at the other parent's home, who the other parent apparently didn't want the evaluator to meet.

It would show the evaluator that the other parent wasn't being entirely forthcoming about the living arrangements -- and that could influence the report.
