Max and Liz’s confrontation at the drive-in ended with Max explaining that he hadn’t murdered Rosa, but that’s not the end of the drama on “Roswell, New Mexico.” The synopsis for Season 1, episode 4 teases more trouble.

“Fearing that his identity will be uncovered, Max (Nathan Dean Parsons) is conflicted when a town-wide power outage leaves patients at the hospital in need of help,” the CW’s synopsis says. Helping Liz (Jeanine Mason) was one thing, but it would be awfully hard to explain the alien handprints if they appear on dozens of patients.

“Where Have All The Cowboys Gone?” is the title of episode 4, which will also feature Liz passing along some details to Kyle (Michael Trevino). In the last episode, Max revealed that he had seen Rosa before she died that night, and he didn’t try to stop her or get her home safely. He wasn’t, however, involved in her murder.

“Liz turns to Kyle after learning details about the night Rosa died,” the logline teases. She’ll probably fill him in on the fact that Max is innocent, but Kyle still has Manes to worry about, though.

In “Roswell, New Mexico” episode 3, Kyle gave some of his dad’s letters to Manes (Trevor St. John). They might send the military man on a new path. “Master Sargent Manes seeks help from an unlikely source.”

Liz, meanwhile, should be concerned about Isobel (Lily Cowles) and Michael (Michael Vlamis). Max’s alien siblings thought they’d get rid of her by using a little mind control, but Isobel learned that Liz is in love with Max. That revelation won’t make the aliens feel better about a human knowing their secret.

“Elsewhere, Isobel and Michael come up with a plan to deal with Liz,” the description reveals.

The promo video shows Michael telling Isobel that she can’t walk into the mind of a dead person. Will Isobel try to connect with Rosa? Plus, the “Roswell, New Mexico” trailer shows Max asking Liz to reveal her true feelings.

“Roswell, New Mexico” Season 1, episode 4 airs Tuesday at 9 p.m. EST on The CW.
