When Harry gave himself up to be killed, his revival is attributed to the fact the Voldemort took Harry’s blood for his own rebirth:
How does this work? Lily’s charm was supposed to disappear when Harry came of age, which had happened already. Why should the charm last in Voldemorts body after that? “His body keeps her sacrifice alive”?! And why does Voldemort die, if he DOES have that protection? Why doesn’t he receive the option to come back down?
And why back in Godrics Hollow, the first attempt at Harry’s life, did he not go to “Kings Cross” and receive an option to move on? Surely it was the same charm that saved him both times?
