This is a question on Gone World.
At one point, Shannon gets back in time without the formal channel (i.e. getting on her ship and heading back over a period of 3 months). She actually uses the time-space anomaly created by the Libra to get back to her time. Once she gets back, she is found by her team and is treated for her wounds.
My question: Since she didn't use the designated way to get back in time, her time, shouldn't there have been two Shannons when she got back? She did slip through the space-time to get back to the 90s meaning, she slipped into a timeline that is not hers. There should have been another Shannon living in that timeline. No?
