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).
