Doctor:
The Professor?  Well, back then
we couldn't cure him.  But we can
cure someone with that sickness
today.  Oh, you want the cure?  I
could make it with your help...

To make the cure I need two rare
ingredients:  A leaf from the
tree of healing and pure water
that's been contained for at least
1000 years.  All the other stuff
we already have.  Take this bag to
carry the ingredients.

Got bag.
