Shaw comes back after she is turned by Samaritan,and she points the gun at team TM.
Root: sweetie, please don’t do this. You are not yourself right now. Remember the someday we talked about? That’s the reason I hold on for so long. I will not let you hurt yourself again. Please trust me.
Harold: Ms.shaw, I am sorry. I gave up hope on you. Guess you are not the only person I have failed. But please, let John and Samantha go. I am the one who is responsible for everything.
John: Shaw, we will find a way to get Samaritan out of your head. We will protect the world and work on numbers again.Now put down the gun or I will have to shoot you.
