LizVega:
Molly calls, the one she assumes to be Fred, Fred. She apologizes 
when they tell her she was wrong, but after that, when 'fred' goes 
through the barrier, and tells her he was only joking...she still 
doesn't know the difference. If my mum was looking at me and my 
sister, she might call us by the wrong name, but if she was looking 
at us while she said it, she would know she made a mistake. Molly 
didn't know the difference. And, what did George say to her?, "And 
you call yourself our mother?" How odd that he says that!

Bookworm:
Reading the scene, I have always chalked Molly's reaction up to 
being distracted with trying to get everyone on the train, and also 
ignoring just another joke from the twins. But put together with 
Molly's comment when Ron got his prefect's badge....hmmm... You are 
right – how odd. 

Let's see, we have the strange comments about the twins, the big gap 
in ages between Charlie and Percy, the unspecified relationship to 
the Blacks along with the comment that all pure-blood families are 
related... What other Weasley mysteries have I missed?
