I really liked this episode very much. Either it was seeing Carter trying to free Reese, Finch working as a substitute teacher or Fusco running errands for Finch, this episode balanced these aspects pretty well. I loved seeing Finch talking about 'Pi'. He would make for a great teacher.
This week's POI was also an interesting one. He was the victim and the perpetrator. Man, these writers know what they're doing and they do it with remarkable ease. Nice acting from the actor playing the POI, too. Loved the emotional part of this episode.
Who didn't love the scene at the train station with Finch convincing Caleb? It was excellently executed. This episode made me actually love Finch's character. I hope that we get info about Finch's life as a student or his early years.
Lastly, but not the least, very little Reese. It was change that I didn't think I would like but it resulted in more screen time for the characters notably Finch and Fusco.
Can't wait for Carter's interrogation of Reese next week. !!!!
