If Ben died as a child he couldn't have been the cause of them being back in time.
If they didn't go back in time then Ben wouldn't have died as a child.
If Ben died as a child he couldn't have been the cause of them being back in time.
If they didn't go back in time then Ben wouldn't have died as a child.
If Ben died as a child he couldn't have been the cause of them being back in time.
If they didn't go back in time then Ben wouldn't have died as a child.
