Criminal Minds Season 15 is expected to answer all the lingering questions fans have. As it will be the last and final season, it will surely tie all the loose ends to give a proper conclusion to everyone's story.

In the previous season finale, fans saw J.J. (A.J. Cook) confessed how much she loved Reid (Matthew Gray Gubler). J.J. admitted she was too scared to tell him about it before. However, things are now more complicated to say it.

In an interview with Cook, the 41-year-old star revealed fans would know what would happen next after J.J. expressed her true feelings for Reid, per TVInsider. It would also feature how her revelation would affect her marriage.

Elsewhere, the previous season also showed the team's encounter with Everett Lynch (Michael Mosley). However, he managed to run away after him, and Rossi (Joe Mantegna) had a face-to-face. Everett managed to bring the FBI agent down with a cut on his forehead, while the knight was lying on the ground next to him.

Daniel Henney, who plays Matt Simmons, said Criminal Minds Season 15 would have more of an arc through episodes compare to previous seasons. Their UnSub, Chamelon, would surely be up to a lot of gruesome and creep stuff this time.

Kirsten Vangsness, who plays Penelope and also co-writes series finale with showrunner Erica Messer, revealed they tried to put as many little Easter eggs and plot tie-ups as they could in Criminal Minds Season 15. This move is said to be for both fans and them.

As this will be the final season, fans can expect to see their fan-favorite characters for the last time. For 15 years, stars have come and gone from the series. However, some remain until today. As there are no words yet if there will be new faces and returning characters in Criminal Minds Season 15, here are the three original characters that fans will continue to see on the final moment.

Of course, fans are about to see Mantegna for the last time, portraying his role as David, Pop Sugar noted. He has played the role since 2007 since he joined the show in Season 3. Rossi will do everything to put down his greatest enemy while trying to hold the team together.

Criminal Minds Season 15 will be final moment fans will see the man of the hour, Spencer, as he tried to solve all the issues in the team and his personal life. The final season is expected to be out later this year on CBS.
