Remember when Ned told Chuck he killed her dad? That was bad. Well, this week, we flash back to that fateful day when the terrible deed happened, and when we flash forward again, Chuck has run away. Ned searches for her, walking the streets, moaning her name, but she"s hiding out at Olive"s, having sworn her to secrecy. And since she"s on the lam, she has to have Olive bake the weekly Aunt Pie, into which Olive puts extra-extra herbal mood enhancer. Oops. But these facts are not yet the important facts. Those facts are these: An insurance adjuster was found frozen to death in the street, and Emerson and Ned have taken on the case. Ned"s all distracted by the absence of Chuck, afraid she"s out there all alone in the world. In fact, however, she"s not at all alone -- our old friend Oscar Vibenius has arrived. He"s been curious about the scent-o"-death on Chuck and Digby since he met them, and comes creeping around looking for the answers to their secrets. Alone on the case, Emerson goes off to interview suspects and finds yet another dead body buried inside a snowman. It"s another adjuster from the same insurance company. Apparently, these dead guys had each denied a certain teenage boy his chance for a new heart. While waiting outside the kid"s house for the killer to show up, they almost get killed themselves. However, they pull it together fast enough to save the good adjuster and solve the case. Finally, when Chuck can no longer bear holding in those secrets any longer, she turns to Oscar, but before telling him the truth, she changes her mind. Ned"s the only one with whom she wants to share her secrets. But, oh my friends, speaking of mysteries unknown-- while drugged up on an overdosed herbally enhanced pie, Lily drops the biggest whopper of all. She"s Chuck"s mother.
