Pushing Daisies/Recap/S2/E12 Water and Power

The Past
Young Emerson, who is usually well-behaved, has been getting into trouble at school. School officials are baffled, but the real reason is that Emerson has a crush on the school principal, and has been acting out in order to get sent to her office. Emerson learns that Love Makes You Stupid.

The Present
Despite not being in love with her and having a lover of his own, Ned finds himself jealous of the budding romance between Olive and Randy Mann. In spite of his irrational emotional response, he does his best to wish the pair well.

The investigation into the death of the Papen County Dam's owner is complicated when the prime suspect--Emerson's ex, Lilah--shows up and demands that Emerson exonerate her. If he does, she'll let him see Penny.
