After the battle of Hogwarts everyone thought that Fred had died, however he had cheated death. There was one twist to this though, he had no memory of what had happened, who he was, or even where he was. Hence why the Weasley clock always pointed his face towards lost. The only way to regain his memory is to see one of his family members out in public. He is not able to travel towards his where his family is located. Once he finds his twin he will be happy forever #humblesimmer
