Criminal Minds season 15 episode 8 is coming to CBS next week, with the title "Family Tree." The series is now nearing its ending and some of the characters' future is now in question. For instance, the upcoming episode sees JJ and Prentiss contemplating on either staying or leaving BAU.

There have been signs that JJ and Prentiss may bid goodbye to their jobs, and the upcoming Criminal Minds season 15 episode 8 proves that will likely happen. They need to make an important decision about their future as the BAU heads to Beaumont, Texas to investigate a series of murdered businessmen.

These two have a lot of things to consider and they need to make the right choice. JJ and Prentiss know being part of BAU is rewarding, but it can be stressful and dangerous at the same time. They are constantly putting their lives on the line to save others and threats follow them as well. Perhaps, these two wanted to have a peaceful life now.

As for Prentiss, she rekindled her flame with Andrew and even joined him and his daughter for dinner, which is a huge step for Prentiss. She's been missing him ever since he and his daughter moved elsewhere. And now that they're getting along very well, will she finally decide to move in with Andrew?

JJ, on the other hand, probably wants to leave because she's constantly in danger and her family wants her to stay alive. Everett Lynch's daughter almost killed JJ earlier this season, so it only makes sense she wants to leave now to be safe and to stay alive.

Moreover, the title of Criminal Minds season 15 episode 8 is "Family Tree," hinting that JJ and Prentiss will choose what's close to their hearts over their job. However, things could go the other way for Prentiss; she might end up choosing BAU over Andrew.

There are only three remaining episodes before the series officially concludes, so viewers should expect some unexpected twists and turns before tying up all the loose ends. It's also interesting to see how Lynch will be part of all of these and how his return plays an important part as the show ends.

Criminal Minds season 15 episode 8 is arriving on Wednesday, Feb. 5, on CBS. Meanwhile, the two-part series finale will be airing on Wednesday, Feb. 19.
