Ep 3. Untouchable

Dr. Helen Magnus and her team of Sanctuary operatives are faced with a new challenge in season 4 episode 3, titled "Untouchable." The episode sees the group investigating a mysterious series of murders that seem to be linked to a young woman with the unusual ability to render people immovable with a single touch.

The episode begins with Will Zimmerman discovering the body of a murdered man in an alleyway. As he begins investigating the crime scene, he notices a strange symbol etched into the victim's forehead. When he reports back to the Sanctuary, he learns that this is not an isolated incident - there have been several similar murders all over the city.

Helen Magnus and the team begin analyzing the evidence, and soon discover that the murders are linked to a person with a unique ability - the power to render people motionless with a single touch. The team realizes that whoever has this ability must be behind the murders, but they have no idea who this person might be.

As they continue their investigation, they come across a young woman named Emily, who seems to be connected to the murders. Emily has been living on the streets, constantly on the run from the police and other dangerous groups who are after her. She is terrified and alone, with no idea how to control her ability or to go about living a normal life.

The Sanctuary team takes Emily in and tries to help her learn to control her power. Will begins to form a strong bond with her, as he tries to help her come to terms with her ability and deal with the guilt she feels over the murders she unintentionally caused. Meanwhile, Magnus and the rest of the team continue to investigate the murders, hoping to catch the real killer before more innocent people die.

As the episode progresses, the team discovers that the person behind the murders is not Emily, but someone else entirely - someone who has been using her as a pawn in a much larger scheme. With the help of Emily and her power, the team is able to track down the real killer and bring them to justice.

Throughout the course of the episode, the team also deals with their own personal issues. Magnus continues to struggle with her relationship with Will, while Kate is dealing with the aftermath of a recent trauma. Despite their own problems, however, the team is committed to helping Emily and stopping the killer before it's too late.

In the end, "Untouchable" is a gripping episode that addresses issues of power, responsibility, and morality. The Sanctuary team is faced with a difficult moral dilemma as they must decide whether to protect Emily, who is essentially a weapon, or turn her over to the authorities and let them handle her. As always, the team rises to the challenge and uses their unique skills and abilities to solve the case and save lives.
