i love all these ideas
they are great
i still think that maybe Lily was the divination teacher
cuz dumbledore needed a new teacher just b4 harry was born (she could have been on maternity leave, and didnt get to go back, cuz she died soon after. Dumbledore might have jsut been looking for a temporary replacement, so thats why he settled on trelawney) and that would be why harry's eyes are so important that he has the same as Lilys, if he has 'The Eye', i think that would make sense
and maybe the dursleys were the nicest relatives that harry had, and Mark Evans' family are evil... :angrysmile: that could be why he was 'giving dudley cheek'
or maybe they arent blood related, only law, and thats why harry needs to stay with the dursleys, cuz petunia's blood can protect him

oh dear, another very long post, coz, i only meant to tell u guyz how observant you are
