Everything Changes sees the Doctor Who Spin-off kick off on a high. The story begins with a murder which is then taken over by a team of experts who have special access called Torchwood. At the murder scene Gwen Cooper happens to see the team of experts somehow bring the murder victim back to life using a glove. As the story continues Gwen starts to try and investigate this team and find out about the mysterious Captain Jack Harkness. This leads her to see a man being torn apart by a monster which she originally thought was a man in a mask. Eventually after close observations Gwen Cooper manages to track down the Torchwood Team and their base which is hidden away underground. Captain Jack Harkness strangely introduces Gwen to the team which consists off Owen Harper, Suzie Costello, Toshiko Sato and Ianto Jones. Jack also introduces her to the creature that she saw kill someone that have been named Weevils. Gwen is soon drugged with a amnesia pill which makes her forget her ever meeting Torchwood. Gwen however soon remembers Torchwood as she starts to piece together the latest murders which leads her back to the Torchwood base to find out Suzie killed the victims. This then leads Suzie to shoot Jack but then shoot herself when Jack stands back up seemly unaffected by the blast. Gwen is soon offered to join the Torchwood team as Jack explains that something happened to him a long time ago and ever since he can not die. Overall I thoroughly enjoyed this episode as I thought the character of Gwen was very clever and I found it started the series of great and keeps you hooked. Overall I would give this episode a 8/10.
