Yes! The band is back together!
I loved the look of anticipation on Root's face as she brought her "surprise" to the meeting at the end of the episode. Harold's look of amazement was pretty priceless, too.
I didn't immediately recognize Shaw at the start. Root being reunited with Shaw as she chased a Samaritan operative from the scene of a hit seemed improbable. Root was getting her tips from The Machine, but I don't know how Shaw was getting her info for taking out Samaritan agents "one at a time." Root's mutual suicide solution to Shaw's continued confusion over simulation vs. reality was a real gamble that paid off.
The cast of characters and roles within roles inside the police station was mind-boggling. Amir's facial transformation from innocent cab driver to hardened hit-man after Fusco called him out was amazing.
Easton's tears over his kidnapped wife were convincing. I did not see him as The Voice at any point before that fact was revealed. The bombs and Templarios were a complex smokescreen for Easton to execute Amir in keeping with his "cleanliness is all" policy.
Pairing Harold and Elias was great. Easton being surprised by Elias having Harold for a partner was a hoot. An unarmed Harold catching Easton after he had eluded Reese and Fusco was a surprise. Elias blowing Easton off the street with the car bomb was not so unexpected.
"Come on Harold. You brought me for a reason. You must have known I'd do something like this."
I was glad to see Fusco finally brought into the loop, although he did seem to be getting over his funk as he and Reese battled the baddies in the precinct house. Luckily for them, the Templarios were no better marksmen than most of those they've faced throughout the series.
