Episode 7 of 'La Brea' is certainly a mixed bag -- with conflict, family resolution, hints of a mysterious past and a possible romance or two, the episode aims to answer some questions, without giving it all away. The episode focuses on Gavin's (Eoin Macken) past, Marybeth (Karina Logue) and Lucas' (Josh McKenzie) relationship and Ty (Chiké Okonkwo), who manages to make a friendly alliance with a person from the settlement.

'La Brea' Episode 6: Eve stops Levi's rescue mission as Gavin fails to save survivors

In the modern-day, Gavin has given up his mission to save Eve and Josh, signing an NDA and narrowly avoiding jail time. With no clue of where Aldridge is or why she abandoned the mission, he and Dr Nathan (Virginie Laverdure) start piecing the mystery behind the date she mentioned -- November 16, 1988. Alridge ominously mentions that Gavin should 'Go back to the beginning' and 'remember that date'. He reveals that it was actually the day he was adopted, setting him and Dr Nathan on a not so wild, rather short goose chase. Gavin finds out that he was found on the side of the road with a 12-year-old girl, with no memory of who he was, his name or where she came from. His visions continue and he soon finds that Diana is dead, a fact he doesn't hide from Dr Nathan. Distraught but determined, she continued to help him. They soon find the girl Gavin was found with, an artist named Ella. Upon visiting her studio, they find a rock sculpture, tying her to the world under and moreover raising more questions about who Gavin is.

Down under, a mutiny is forming as the survivors vote that Marybeth and Eve (Natalie Zea) should leave the group, as Marybeth refuses to give up her gun causing the others to feel unsafe. The ultimate betrayal for the two comes when their own sons vote in favor of their exit, as they as still upset over the rescue mission being jeopardized. While they get ready to leave, a massive ice age storm is brewing, causing a structure where Lucas is taking shelter to collapse. Marybeth attempts to save him only to find herself trapped there as well. With both of them cornered and Lucas' claustrophobia kicking in, Marybeth helps her son calm down, even though he maintains he despises her. As a part of the rescue mission, Josh (Jack Martin) and Riley (Veronica St. Clair) brave the storm to find an 18 wheeler they hope has the equipment to help, as Eve relentlessly moves rocks and even tries to dig a tunnel.

Back inside, Marybeth comes clean about why she killed Lucas' father -- his father was a cop stealing drugs from the department and soon the IA was on to him. However, he cut a deal where he walked free and pinned the blame on Lucas. Marybeth was not ready to watch her son's life be destroyed and was left with no option but to kill Lucas' father. Lucas has a hard time believing his mother, who points out that they might die here and she has nothing to lose. Fortunately, they make it out alive as Sam builds an IED and manages to blow a hole in the debris. Josh and Riley on the other hand find the truck, but turns out, it is a clothing trailer. They decide to wait out the storm, where Riley talks Josh out of hating his mother for what she did. They share a tender moment and almost kiss, but it ends as soon as it started, much like the storm. 

Meanwhile, Ty is found and reluctantly nursed back to health by a mysterious woman named Paara. Hiding from the storm together in a cave, Paara explains that the 'sky people' are not to be trusted, but Ty shows her otherwise. He opens up about his divorce and life back home, as they talk. When the storm settles, a one apprehensive Paara seems more forthcoming -- she offers to help him find his way home.
