The Benefactor Ep.04

In the events of the last episode, Derek and Sheriff Stilinski examine the Wendigo's body after the Mute's attack. Scott and Stiles take Liam back to his house, but he escapes just before they can fill him in on what he saw and Peter is attacked by the Mute. The next day, Malia and Stiles prepare for the full moon and Lydia and Kira try to decipher the computer code that Lydia wrote down in Malia's math notes. Liam soon starts exhibiting his werewolf powers and Scott and Stiles unsuccessfully try to gain his trust. Without Liam's trust, Lydia suggests that they trick Liam into getting him to Lydia's lakehouse and Kira manages to convince him to go with her. Derek painfully fixes Peter's wound, but Peter shows him a glove he got off the Mute during the fight. At the lakehouse, Stiles learns that Liam was kicked out of his previous school after a violent attack on a teachers car. Derek brings the glove to Stilinski, but Parrish identifies both the glove and the Mute's tomahawk as military equipment. Liam is brought to the lakehouse and is brought up to speed on the supernatural, but both he and Malia begin to lose control. Worse still, Liam texted his friends and others that there was a party there. As Lydia distracts the guests, Stiles hides Malia in the basement and Scott and Kira get Liam into the boatshed. Parrish, Stilinski and Derek discover that the Mute is an assassin hired by someone called the Benefactor. At the party, a werewolf is killed by one of Liam's friends who is also an agent of the Benefactor. Kira teases Scott about his self-control on a full moon, but Liam loses control and escapes. Malia struggles with her restraints, but Stiles, with his experience with the Nogitsune, helps her gain control over her transformation. Derek and Stilinski find the Mute at the school and when a trap was foiled, the Mute attacks them directly. Derek disarms him, but Peter intervenes and kills him. Scott finds Liam in the forest and thanks to Chris Argent's arrival, he learns that Liam fears that his parents will look at him like a monster like after his attack on the teacher's car. Scott assures he is a werewolf like him and thanks to her own abilities, Lydia deciphers the code and discovers a deadpool, a list of supernatural beings living in Beacon Hills.

117 Ep.02

The opening scene shows young Peter asking young Derek to learn to control his werewolf abilities, using an artifact known as the Triskelion. In the present day, Kate brutally kills a gas station attendant, and appears to be unable to control herself when transformed. Scott and his friends, who have returned from Mexico, take Derek to Deaton, who is baffled by Derek's regression. Lydia stays with Derek overnight while Scott and Stiles return home. In the morning, Deaton finds out that Derek is healing in an unusual manner - he heals much more rapidly than usual, and he has a high fever. Later, as they begin another experiment, Derek awakens, but is disoriented and confused. He attacks Deaton and disappears. He is later found by two sheriff deputies near his destroyed house. Scott teams up with an unlikely source - Peter - in the hopes of putting an end to Kate's evil plan, which involves using Derek to get into the Hales' family vault (under the high school) and find the Triskelion in order to learn control over her shift. Scott, Peter, Malia and Kira re-encounter the creatures that attacked them in Mexico, which Peter identifies as Berserkers. Scott, Kira and Malia fight the two Berserkers, but are easily defeated. Peter confronts Kate and Derek in the vault, where he explains that the Triskelion was just a trinket for Derek to focus on; Derek learned control by focusing on his anger. Derek goes to help Scott and the others, and engages the Berserkers in combat. Peter faces off against Kate, but they are interrupted as an unknown individual blinds them using flash grenades. Kate flees, and the new arrival steals a briefcase from the vault and leaves while Peter is blinded. The Berserkers run away when Kate calls them, and Derek reverts to his normal age, but with yellow eyes. Stiles and Lydia find Peter alone in the vault; he explains that the whole thing was a heist, and that $117 million worth of bearer bonds were stolen from the vault.
