the ending of the homicide case. ''Haha, it was the temp bartender all along!'' just seemed really lame and anti climactic. Especially given that you don't get a commendation for it or anything.
Honestly, I didn't even remember him like five minutes after meeting him. I had no idea who it was, so I was expecting somebody a little more prominent. I don't know who it would have been, but it just seemed like such a random thing.
