Problem with the solution, and Spoilers
Here's my question. Please help me out. Tell me if I'm missing something.
So Callie thinks that she can erase what just happened, the death of Finn, by sending herself a message from 8 AM the next day, back to her "present" day, at 8 AM when she killed Finn. But she didn't get a chance to get the photo. Finn caught her taking a photo at 8 AM. Then, about 5 minutes later, he's dead. She didn't go over there to get it. So how was she supposed to receive the message? Even if her plan would have worked, and time could be changed, how could she have gotten the message?
