Hats off to whomever realized the Pidgin "lady" is Brett Partridge. I checked the video several times in slow motion and that's definitely a man In loose, frumpy clothing. He writs, hands and shoe size are very large for a woman. The writs look slightly abraded from the zip ties and if you compare the woman's facial profile to Brett's, you will notice they match with the elongated facial structure, pronounced nose. Also, her 'natural' hair color matches Brett's with RED highlights in the wig.

Red John was baited to come out of hiding to listen to what Lisbon/Jane had to say because Jane dropped a hint about knowing something Red John didn't while in Bertram's office.

He's not afraid of birds. The dead psychologist picked up on his growing fear of Jane discovering him. That's the real reason he visited her and what was immediately on his mind.
