Frosine Timeline and Summary

Frosine shows up and greets La Flèche, since they seem to have a prior acquaintance. She informs La Flèche that she has decided to play matchmaker between Harpagon and the young Mariane, hoping to score a little money in the process.
La Flèche tells her she'll never get any money out of Harpagon, and she is disappointed to find that this is true.
When she finds out that Cléante and Mariane are in love, Frosine agrees to help them hatch a scheme to get Mariane away from Harpagon. She plans on getting one of her friends to pretend to be a rich old lady who's interested in marrying Harpagon.
The plan never comes off, though, as Harpagon sniffs it out (and snuffs it out).
