Hi,

i've been reading all the comments about Lupin, and I'm very curious to know
why some think he will turn out to be an evil character, and why some think
he may have killed Sirius.  He seems to me, to be one of the kindest and
most compassionate members of the order.  Where does it say that he is an
habitual liar?  Is there anything in his adult life in canon to support
these theories?  i don't count what he did in school, because I don't know
any mature adult who is the same now as they were in their teenage years.
