when does spencer become part of the a team
Spencer Hastings She gives the key to a private investigator and gives him a picture of Toby and her, before ripping it in half. She tells him in order to find where the key leads to, follow him. He leaves and Spencer disturbingly begins to rip her own half of the picture of herself. She begins to withdraw herself from her friends, and becomes emotionally unstable. She is angry, and starts to unravel and do things she knows she shouldn't (attacking Mona physically, and telling Jason that Alison was pregnant before she died with Darren Wilden, but had no physical proof). In the episode "Hot Water" she tells the girls the truth about Toby. Also in the same episode, she catches a glimpse of the girl in the red coat who is the leader of The 'A' Team, but fails to catch up with her. In the episode "Out of Sight, Out of Mind" she finds Toby's dead body and tells him, "I love you". After failing to track Mona down in the woods she is found by a hiker in the morning with small injuries to her face and arms and is admitted to the Radley hospital in a catatonic state. She is unknown by doctors at the time and is simply known as, 'Jane Doe'. When her identity is revealed to the Radley staff, Mona visits her. They have a long discussion and it is revealed in "I'm Your Puppet" that Mona somehow convinces her to join the A team. Spencer is the third known member of the A team.
