Second, I like to think this is a moment for all three characters to shine. Lilly has had enough limelight and I'm happy with her character development. It's not over for her but it shouldn't all be about her (much as I would love to) ;)
Third, Jenny is not just her power... Time she learned it takes wit, cunning, and a good number of friends.
