After Ioki is shot and left in a coma, the other officers decorate the board by his hospital bed with pictures that might bring him comfort when he wakes up. One of which is of his grandmother but she is clearly much older than she was in the flashback episode which means she must have sent it recently, a Continuity Nod to the episode when Ioki is able to locate and contact her.
How Hanson offers to go to El Salvador with Doug—at that time a civil-war-ridden country—when Doug says he wants to go look for his wife there. Doug himself is hesistant about Hanson coming, as it is dangerous, but Hanson makes it clear he will stand by his friend—and he does; they get into a few life-threatening situations in El Salvador, but stand by each other.
And then how Doug decides to adopt Clavo when they are in El Salvodor and find out Doug's wife has been murdered, but do meet his wife's sister and her son Clavo. Doug is consequently shown in his remaining episodes to have taken Clavo home and to care for him, giving Clavo a new life.
The Movies:
There's something oddly sweet about the fact that, in spite of the time spent ripping the premise a new one, the film is incredibly faithful to its predecessor: it reunites the core cast even if two members get shot to hell, insists that the church is the same and any decor changes are only due to it being leased out, and even making its lead the son of a short-lived and forgotten first season character.
The training montage, with the development of Jenko & Scmidt's friendship.
When Jenko activates the phone tap & overhears Schmidt struggling to ask Molly out, he seems so proud when he actually manages to spit it out. Of course, the moment's ruined when he overhears Schmidt making fun of him.
Hanson's last words to Penhall.
"Doug, I know sometimes I was a jerk to you when we were undercover. I just...I didn't feel good about myself. All the stuff I wore like, the bracelets, the rings, the tight pants. It was just so that people would think I'm cool. The only approval that I ever needed...was my best friend."
