Vangsness and Messer kicked off their collaboration with Season 10, Episode 13 (“Nelson’s Sparrow”), in which the team has to revisit the origins of the BAU in the wake of veteran Agent Jason Gideon’s (Mandy Patinkin) murder. Their next tale would put the team to the test in Season 11’s “A Beautiful Disaster,” as a crime boss strikes up a feud with Derek Morgan (Shemar Moore). Vangsness and her writing partner also penned the Season 12 episode “Spencer,” which features Agent Spencer Reid’s (Matthew Gray Gubler) arrest by Mexican authorities on drug possession and murder charges. The BAU team has to put out all the stops to ensure his safe return.
One of Vangsness and Messer’s last two “Criminal Minds” episodes was Season 13’s “Full-Tilt Boogie,” which sees the unearthing of secrets in a small town after a brutal home invasion homicide. Their last collaboration came in the Season 15 series finale (“And In The End…”), which brought down the curtain on “Criminal Minds” until the recent announcement of the series’ potential revival.
Vangsness and Messer’s collaboration on a number of “Criminal Minds” episodes definitely provided some suspenseful and engaging viewing. While the future is uncertain, we can enjoy the “Criminal Minds” episodes that Kirsten Vangness co-wrote with Erica Messer and hope that maybe, one day, we’ll get to see more.
