SUMMARY:
Years earlier, Peter teaches Derek how to control his shift, using an artifact known as the Triskelion. In the present day, Kate kills a gas station attendant, and appears to be unable to control herself when transformed. Scott and his friends return from Mexico and take Derek to Deaton, who is baffled by Derek's regression. Derek attacks Deaton and goes to his destroyed house, but is arrested. When Kate abducts Derek from Scott's house, Scott teams up with Peter to put an end to Kate's plan. Peter identifies the creatures that attacked Scott as Berserkers . Kate and Derek access the Hale family's vault under the high school, and Kate wants the Triskelion in order to learn control. Scott, Malia and Kira take on the Berserkers, but are defeated. Peter confronts Derek and Kate in the vault. Derek leaves to help Scott, while Peter explains that the Triskelion was only ever a trinket. With Derek gone, Peter and Kate fight, but are interrupted when an individual blinds them and steals a briefcase. Kate flees and Derek reverts to his normal age. Stiles and Lydia find Peter, and he reveals that 117 million dollars were stolen.
