“American Horror Story: Hotel” answered a lot of questions for fans throughout episode 4 -- like how The Countess (Lady Gaga) was able to kidnap Holden (Lennon Henry) in the middle of a bustling carnival, the reason behind Mrs. Evers’ (Mare Winningham) heartbreaking sheet obsession and who might just be the Ten Commandments serial killer. It has to be Detective John Lowe [Wes Bentley], right? 

We first became suspicious of Bentley’s tall, dark and handsome -- not to mention empathetic -- character after he was portrayed as a “too-good-to-be-true” sort of guy in the “Hotel” premiere. While some men were getting their eyes gouged out for infidelity and murdered for the mistreatment of their parents, good ‘ol Detective Lowe was reading a sweet bed time story to his daughter. But after watching Season 5’s Halloween-themed episode, we’re more convinced than ever before that the detective might not be as angelic as he seems. In fact, he may be the very same suspect he’s hunting down. Here’s why:

1. You Can Sit With Us – And Kill With Us, Too

In episode 4, titled “Devil’s Night,” John was invited to attend a dinner party with a guest list that included some of America’s most horrifying serial killers. (Think Aileen Wournos [Lily Rabe] and John Wayne Gacy [John Carroll Lynch].) But instead of chowing down on some bug-infested sandwiches, the ghosts used Devil’s Night, a reunion of killers, to rip apart some poor, unsuspecting victim. But, of course, sweet John was totally disgusted by the deadly dinner (because he’s so not a murderer).

“John is clearly not yet our kind,” Mr. March (Evan Peters) said, hinting that John hasn’t fully evolved into a sadistic villain.

2. He Hasn’t Been Killed

This seems pretty obvious, but if John was just a regular Hotel Cortez guest with no significance then wouldn’t he have been killed by now like heroin addict Gabriel (Max Greenfield) or Vogue editor Claudia Bankson (Naomi Campbell)? Like Liz Taylor (Denis O’Hare) revealed in episode 4, Mr. March keeps a watchful eye over his very important guests… and it looks like John is one of them.

3. Suspicious Timing

Detective John is the only one who receives tips from the Ten Commandments killer -- ones that lead him straight to the dead or terrorized victims. Not only is John’s relationship with the killer strange, but we also found it a bit odd that the victims John finds are either dead or blind.

Is the reason that the adulterer had his eyes ripped out during the Season 5 premiere was so he couldn’t identify John as the murderer? Also, how could John even understand the mumbles of the tongueless man who tried to alert officials that his penis was glued inside the dead woman straddling him? Is it because John was the madman who orchestrated the crime?

4. Lust For Control

In episode 4, John tells Liz that the reason his wife thinks he hasn’t had a drink in years isn’t because he’s an alcoholic (which he believes he is) but because he loves having control -- something he lost with the disappearance of his son. This made us think John is living a double life -- one as a control-seeking, serial killer during his drunken blackouts and another as a doting husband and father while he’s sober. 

The Countess also revealed to Alex (Chloë Sevigny) in episode 4 that the reason she took Holden was due to neglect from his father. According to the vampire, she only takes children when she senses their lives are headed toward a dismal fate. Is it possible The Countess was able to sense John's murderous side?
