I have to admit that when I initially heard that Abby's character would be crossing over from NCIS to NCIS: Los Angeles, my reaction was meh. What could they possibly do that would make the transfer of the ultimate forensics goth geek from the cozy confines of her lab in D.C. to the high-tech, touch screen caravan in L.A. compelling?

Well, I tip my cap to Speed Weed (that has to be an alias!) for writing the episode, "Random On Purpose," which struck me as one of the best examples that NCIS: Los Angeles is coming together pretty nicely. I could definitely see now how this show is evolving. More on that and the rest of the episode (including spoilers -- be warned -- after the jump).

(S04E06) Fans of Reno 911! know there's been a running gag since the first season in which Dangle always has his bike stolen from him in broad daylight, even when he tries to lock it to something. In the opening scene of this episode he thinks he's found a fool-proof way to catch the person that keeps swiping his bike: he uses a special mirror to hide behind a building and peer out at his bike. Unfortunately, just as he gets the mirror adjusted somebody zips by on his bike and grabs the mirror.

After the opening credits we get into the real meat of the episode, which begins with Sheriff Chechekevitch being hauled into an ambulance and telling Dangle to avenge his death. Chechekevitch also appeared in season two during a three-episode story arc when Jones and Garcia were being charged with murdering a man dressed as a milkshake. The deputies all love him, at least, they think he was pretty good for a Polish sheriff. Really, they've had better sheriffs.
