'Castle' Season 7 Spoilers: Episode 14 Brings Back Killer From Beckett And Castle's Past?

"Castle" season 7 episode 14 spoilers will point to Rick and Beckett facing a killer from their past.

If a killer of Jerry Tyson's caliber is bent on revenge, he would hurt people close to Castle, Cartermatt said.

"While we're not so much worried that Stana Katic is about to be written out of the show, we are concerned that she could be the one in major danger in this episode," said the article. "After all, there is no one who 3XK could threaten to hurt that would impact Rick more than either her or Alexis."

One thing that insulates Alexis, however, is that the show has already put her in danger so many times in the past that carrying on that theme on this episode would be "a little more stale." For the producers to mix it up, Beckett has to be placed in danger's way, said Cartermatt.

Spoilers for "Castle" season 7 are gleaned from the synopsis which reads: "Clues in a young woman's mysterious murder, will point to a suspect Castle and Beckett have dealt with before, Dr. Kelly Nieman."

"When clues in a murder implicate Castle and Beckett's nemesis, Dr. Kelly Nieman, Castle will get called in to consult on the case. But as the team delves deeper into the investigation, they are going to uncover connections to notorious serial killer, Jerry Tyson, on Part 1."

As fans know, Jerry Tyson is also known as 3XK or the triple killer whose favorite targets were blond women, and his favorite M.O. is to strangulate them and to arrange their bodies-hands clasped in front of them-to look like they are sleeping.

This particular episode is directed by Bill Roe and written by David Amann
