This was a well-played episode and the storyline seems to be going along the line of the day-to-day grind of solving cases. This case was rather unique in it's setting, but progressed along the Jane-ish approach as expected.
Bonus points for Lisbon taking Van Pelt over Rigsby to the crime scene. Ribsby seemed rather suprised/annoyed, but his eventual appearance at the reunion was very entertaining. Maybe his newly learned skill from Jane will pay dividends at a later date.
A little more information about Lisbon's and Jane's past came to the surface and their dance at the close was quaint yet reserved.
Cho's restrained intensity was visibly evident in his facial expression with the board in his hand as he fended off the attacker. There was a hint of experience in that whack!
The "red" theme was obvious throughout. The episode's title, "Rose-Colored Glasses," the red-headed murderer, and the name of the high school, Rancho Rosa[Spanish for (Rose-flower) or (Pink-color) Ranch]. Looking for the "red" is like playing "Where's Wally(Waldo?)." It might be fun to start a forum game to find all the references to red in each episode.
This series continues to be top-notch and is maturing as any long-running show should in order to remain sustainable.
