End of Nights

The episode follows from the season one finale, "Revelations", where the Cabal launch a weapon named Lazarus to turn Abnormals against Humans.

Six weeks since the events of "Revelations, Part 2", Helen Magnus (Amanda Tapping) and John Druitt (Christopher Heyerdahl) travel to Egypt in the search for Ashley (Emilie Ullerup), but learn that the daughter they knew is dead.

Meanwhile, Tesla (Jonathon Young) is able to create a cure to the Lazarus virus, though Bigfoot (Heyerdahl) refuses to take it due to the fact it was developed by Humans.

The team find out about the break-in in Montreal, and discover that the files Ashley stole concern "Operation Montana", a British government operation to experiment on six orphans 25 years previously, to turn them into "perfect" humans, until Magnus shuts it down after she deems it a rebound of the Nazi eugenics programme.

[1] Henry and Druitt recover the fifth Montana subject in Essex, while Magnus and Will Zimmerman (Robin Dunne) search for the sixth in Vancouver.

Will, Druitt, Tesla and Magnus arrive at the warehouse to find Ashley is alive, but is now fully transformed into a seemingly indestructible Vampire hybrid, and that her original personality is destroyed.

The team manages to drive off the hybrids with a fire elemental which forces them to retreat, but the London Sanctuary is badly damaged.

Now with a fully functioning weapon, Magnus is able to kill three of the hybrids before she confronts Ashley, and attempts to talk her into coming back.

After Bigfoot takes the cure and saves his friends, he protects Henry and Will while they restore the EM shield, which destroys the fourth hybrid when he attempts to teleport.

The final hybrid attacks Magnus, but is stopped by Ashley, whose original personality (apparently buried, not destroyed) manages to regain control of her body temporarily.

Visual effects were added in replacement of the green screen, for background to make the Cairo street look longer than the alley was.

The scenes between Christopher Heyerdahl as Bigfoot and Ryan Robbins as Henry Foss were completed on one take, because Wood was impressed by the acting and the camera angles.

[3] The ratings for the second part, however, dropped slightly to 1.77 million, though this still made Sanctuary the sixth most viewed series on Syfy the week it aired.

Simpson also stated the scripting felt a bit sharper, though still high on melodramatic dialogue, and described the introduction of Kate Freelander allows a degree of fun.

[7] URBMN was mixed towards Christopher Heyerdahl's performance; stating he was uneven as Bigfoot, but excellent as Druitt, and also found Agam Darshi "surprisingly tolerable" as Freelander.

He stated the first part doesn't leave much room for the newcomers to the series, but still holds a fair amount of interest, and was decently executed, and the low points remain "forgivable."

Vaux believed the action sequences failed to catch hold, but improves with its character developments, stating the best moments involve Ashley's indoctrination, and Babz Chula's "creepy performance.

Damian Kindler wrote both parts of "End of Nights".
Christopher Heyerdahl 's performance as John Druitt received some of the general praise of the episodes.
