I don't read it as being a complete bitch. She just don't have faith in improvising. She told him that before and in that scene she was worried about him messing with evidence. I think it was a reasonable reaction for someone who has not been in the field with Mac

Meredith Eaton's role is really good glue to keep the team cohesive. She has always been one of my favorite actresses. She is not bitchy, she's the boss and she skirts the line of authoritative and caring very well.

I'm sorry but I am always distracted by the fact she is a little person. I'm not trolling or anything and I have nothing against little people. But it is always awkward in scenes where they shoot her from like knee-height and they are all staring down at her, or she is interacting with them.
Plus I liked Sandrine Holt better. She does a much better job playing the stern, kind of bitchy authority figure. I have seen her play that same role on a few different shows.

I thought her "Encyclopedia Brown" line was funny.

She's not being a bitch. She's being a concerned boss. She told MacGyver that she was afraid his improvising might not get him out of trouble someday and she doesn't want to watch him die.

Yeah she surprisingly picked up the tough boss role well after Thornton left. She's tough but she is fair and caring to her team.

Think they're doing a good job. Tough boss character. Keeps them in line.
