Twins.
Harry Potter's twin brother and his mother are almost cut from the same mold.
When Harry Potter's brother was born, because the Potters did not prepare the name of their second son in time, even though he was a baby, he was exactly the same as Lily when she was a child. The same red hair and green eyes made James Potter make the decision to name his eldest son Lily Evans, yes, after his mother's surname.
Although it was strange for a boy to use a girl's name, it was quite common in the Potter family.
After that, the twins started their school journey.
Everyone who has met Lily said that he looks so much like the last Lily that it is indistinguishable.
He inherited all his talents from his mother, even his voice and personality are somewhat similar.
But the wonderful thing is that no one has ever recognized him as the previous Lily.
