"The desert rose" is a very important episode .
It was stage 1 of Patricks game because Lisbon sprung into action telling Gvp about the list.

*If you watch the scene where Lisbon is stun gunned something A LOT of people missed occurs.

-Partridge is dead at Lisbon's feet. There WAS a person behind the door to Lisbon's left side .
Somebody was also behind Lisbon ! There was a window behind her and that is where she was zapped from and why she fell backwards.
-The was no way Lisbon could have been zapped from anywhere else because her back was to a wall with a window. We are looking at a two person job .
-Partridge was on the ground the door creeked and she looked to her left but the zap came from behind . Check it out again.

Side note: the next day Rigsby calls van pelt and says "last night was incredible " . Now we assume they mean sexually it was incredible but what if they were in that house together and killed partridge and zapped Lisbon?
It makes sense becuase why would red john not kill Lisbon for snooping around?
Also, Macalister was not there ! So he cannot be red john!!
