Lily and Potions

No: HPFGUIDX 133231

All through Slughorn's many pronouncements that Harry had inherited 
Lily's potions mastery, I kept thinking, "no, her wand was best suited 
for charms."  That's what Ollivander said to Harry in SS/PS.  While I 
realize that a person can excel in more than one subject, it didnit 
seem possible that for Lily it would be potions.  So it begs the 
question(s), for me, was Snape helping Lily?  Did she somehow copy 
from Snape's advanced potions book?  How does that relate to Harry and 
what she "bequeathed" to him via her eyes?

HBP is presenting as many questions as it answered.  The more I read 
it (twice so far) the more things jump out at me.
