Matthew Gray Gubler is set to star in a brand new CBS series, and that boosts his chances of coming back to Criminal Minds: Evolution. As an original ensemble member, not having Spencer Reid as part of the cast of Criminal Minds: Evolution has been a big topic of conversation among those who enjoy the series. There was initial confusion on why Gubler isn’t really involved, but ultimately, it was determined that his absence boiled down to scheduling conflicts. The actor wanted to venture out and do something different after playing Reid for 15 seasons on the CBS series.
