'Criminal Minds' Season 10 Spoilers: The Itch Is Coming Next

The FBI's Behavioral Analysis Unit (BAU) will be up against a suspect with a murderous track record and a mysterious skin disorder in Episode 4 of "Criminal Minds" this Wednesday, Oct. 22, at 9 p.m. on CBS.
Titled "The Itch," the episode will see the BAU agents discovering a body in Atlanta covered in scratches. "The BAU is going to find that this death and subsequent murders could be linked to an UnSub with an obsessive skin disorder," the official synopsis of the episode reads.
The 10th season of "Criminals Minds" premiered on Oct. 1 with Kate Callahan (played by Jennifer Love Hewitt) joining the BAU.
In the succeeding episodes, we saw the BAU agents tracking down the suspects in a number of murder cases but failing to catch the actual culprits. In the premiere episode titled "X," the team failed to arrest all the suspects involved in the murders of women who were brutally dismembered.
As the trade of severed limbs continued online, there was a teaser at the end of the episode implying that another person who was kidnapping women and then offering them for sale on the Internet is still on the loose.
Callahan and Agent Aaron "Hotch" Hotchner (played by Thomas Gibson) believed that they had not yet caught all the murder suspects in the first episode although the rest of the BAU team thought they had already collared everyone of them.
Viewers got to see Kate hugging a teenage girl in the premiere, but there was no explanation as to who she was.
The third episode titled "A Thousand Suns" focused on finding the suspects in a horrendous plane crash. Not much was said about Kate's back story. The only glimmer from her past was when she revealed that her sister and her husband died in the Pentagon during the 9/11 attack and that her sister's daughter Meg is now living with her.
As to whether "Criminal Minds" is going to feature a killer whom the team has been tracking all season long, the answer to that is yet to be seen. However, the UnSub whom the team failed to capture in the premiere episode could very well be that person.
