This episode is the conclusion of two part episode. Brilliant drama, original and also very inconsistent. It feels like the writers spent a lot of time rewriting and refining or decided the last minute to make it a two part episode. One example: it takes the entire episode finding a character that is making and receiving phone calls left and right, while another character is found in minutes by tracking his phone. Another: there were numerous big opportunities to get the proof needed but these are all ingnored to have the direct confrontation the writers seemingly required. In an action movie these lapses in the story are somewhat acceptable, but when it is all about outwitting your opponent this stuff for me is a bit harder to ignore.
