剧情简介：
Chuck一大早跑去了Ned的店子，见着了女招待Olive同Emerson，两人都说她像死去的Charlote，不过前者被蒙在鼓里，而后者则一清二楚。Chuck要求加入破案，自己也要分成......

Chuck: I've been ruminating - and by ruminating, I mean pondering, not chewing cud - how about we solve my murder and collect the reward? Wouldn't that be poetic? Certainly an anecdote.
Emerson: She's supposed to be in the ground.
Ned: I thought you didn't want the reward.
Chuck: No, I didn't want you not to want the reward. $50,000, that's a lot of money. Three-way split?30-30-40? It's only fair I get more: I did die for it.
