2) The Mentalist will be wrapping up the Red John story line this week with the final showdown between Patrick Jane and the as-yet unrevealed serial killer Red John, who killed Jane's family years earlier and has bedeviled him ever since. Three years ago, it looked as if Jane had disposed of Red John in the season finale, but in the following season opener it was revealed that the dead man (Bradley Whitford) was merely one of Red John's many minions. This time it appears as certain as it gets on TV that this week's episode will be the final showdown, since the series will jump forward two years in time to the following episode. The producers also came up with a list of seven suspects at the end of last season and claim Red John will be one of the seven, and the first few shows this season have served to narrow the field as most of the seven now appear to be dead. However, being TV, when a master criminal appears to be dead, that's often not the case. Still, I'm pretty sure that there won't be any more stunts like the producers pulled three years ago and that whoever is revealed this week will be the real Red John.
I'm definitely looking forward to these two shows.
