I can't believe that I missed this before. If you see "Red-Hair and Silver Tape", this is kinda a really creepy conversation :

Mcallister : Who is this guy?

Lisbon : He's a consultant. You want CBI assistance, he comes as part of the package.

Mcallister : (@ Jane) Consultant, eh? What are you, clairvoyant or some gizmo? You've got psychic powers?

Why did he come up with the 'consultant' thing in the first place? Also, when you see the look on Mcallister's face, he's not mocking Jane. He's taunting him..
