Was she an alchemist? Asks this week's MuggleCast episode 91. There are certain factors that prove Lily was an alchemist, and they seem to fit. JKR has yet to tell us what Lily and James' jobs were, and she says that there is an important fact about Lily to be discovered.
Could it be that Lily is an alchemist?
She was always good at potions, suggesting a possible career in potions, such as alchemy. She was obviously a very powerful witch, and this would explain why exactly Voldemort gave her so many chances to live. It is entirely possible that he would have taken her on as a Death Eater, or to use against the good side against her will. She was not, however, a Deathly Eater, says Jo.
On the note of Voldemort, it is also probably important to know how he was "thrice defied" by the Potters. While this may be simply in the situation of life and death, and that they got away three times, another idea is that Lily successfully made a Philosopher's Stone--she defied death.
