"Little Fish" juggles two separate plots--a cold case from Frank's past and the murder of a prostitute Danny knew--and both come up a little short. Both cases have the requisite emotional impact on the characters, but neither case has any uniqueness or unpredictability. The dinner "issue discussion" is shorter than it normally is and still went over the topic (facing the accuser) enough to get everyone's idea. Without anything new or different in any episode Blue Bloods seems more and more normal as it goes on.
The Jaime plot was even more stunted than usual with the quick introduction of a cop who used to work with Joe and a warning from Anthony. There's no tease of a possible connection to the Blue Templars or anything more sinister.
Score: 8.4/10
