First, let’s lay out exactly what happened to lead up to the big exit.
Although he was not killed off, he is off active duty and has gone away to recover, and Lutz is out as a series regular.
After the Season 2 finale, fans were left with a cliffhanger as gunshots rang out, though it was unclear who those shots may have hit.
That question was answered in the Season 3 premiere, with the good news that only the bad guy died due to the cliffhanger, but the big crossover case resulted in Kellan Lutz’s Special Agent Kenny Crosby suffering some serious gunshot wounds.
