Rumors were going around that Jennifer Love Hewitt wouldn't be returning as Kate Callahan for "Criminal Minds" season 11. Some speculated that Kate would be killed off the show.

But Zap2it.com can put your mind at ease: the publication caught up with showrunner Erica Messer, who said that "no major deaths" will happen in Season 10.

According to Messer, the finale will reference the beginning of the season. "We will bring back the creepy, Internet stalker guy from the premiere. That story will be tied together," Messer says.

Messer warned, "It will be a very heavy episode for Kate."

Though Kate may have a tough time in tonight's episode, it looks like she'll be back at the BAU when season 11 premieres.
