There are only a few hours to go before fans are going to witness another episode from CBS network's police procedural crime drama series, "Criminal Minds." On the upcoming"Criminal Minds" season 12, people are going to see another scenario on how Spencer Reid deals with the struggles with living in prison.

On the previous episode of "Criminal Minds" season 12, fans witnessed the Behavioral Analysis Unit to have suspected a hacker being responsible for a series of vehicle accidents on the pedestrians in Florida. Meanwhile, Matthew Gray Gubler's character Spencer Reid was also being prepared by his defense attorney, Fiona Duncan (Jeannane Goossen) and Special Agent Prentiss (Paget Brewster) for his trial.

Now as much as many fans wanted Reid to finally find his way out of prison, it has been reported that it will not be happening on tomorrow's episode of "Criminal Minds" season 12. Surely it will be happening in the upcoming episodes but reportedly not in episode 15, according to Carter Matt. Instead, what fans are likely to expect is for Reid to meet new faces, friends, and foes.

As per the source, the BAU team is not going to stop trying to get the doctor out of prison. But while they're at it, Reid is going to meet new people on "Criminal Minds" season 12's episode 15, including guest star Harold Perrineau's character Calvin Shaw. Viewers are reportedly going to see him as Reid's prison buddy for the following weeks, and that could mean for the doctor to stay in jail for a longer time.

Moreover, on the official promo released by the network, Shaw tries to engage in a small conversation with Reid. He tells him that he should know and learn how to survive in prison as the upcoming episode of "Criminal Minds" season 12 will reportedly feature Reid's company in prison to plan in beating him up.

Meanwhile, it has been reported that fans and viewers will see through each episode that the second part of "Criminal Minds" season 12 will be applying its planned major change. As reported by Cinema Blend, the change in the series' character lineup was evident, especially when actor Thomas Gibson got terminated and his character Aaron Hotchner got written off as well.

However, this will reportedly be not only the change that the team behind "Criminal Minds" season 12 will be applying. Through Gibson's departure, the showrunners found a way for the remaining episodes to be unpredictable from the viewers and fans. Aside from that, the written stories for each episode will apparently get more intense and darker as the season approaches its finale this year.

"Criminal Minds" season 12 episode 15 airs March 1, 2017, on CBS.
