Numb3rs has definitely established itself in this third season. So far the episodes have been very well done in every way (acting, writing, storylines) and are very entertaining from start to finish. This episode is defintely no exception. The viewer can certainly understand Don's reasons for doubting the assasin and the stories the assasin told. The final resolution to the assasin's stories is plausible and a logical conclusion. Peter MacNicol's return is another reason to enjoy this episode. Hopefully the winning streak of Numb3rs will continue far into the future.
