Detective Snow is :

a) Beginning to think that he is being "Set Up", and that The Chief may be "On the Take".

b) Beginning to think that there may have been "Something" to his ex-partner's "Wild Theories" after all.

c) Beginning to think that that it was a "Bad Idea" to use his belt rather than the provided holster to store his "Firearm", as it has slipped down the leg of his pants and he currently unable to recall if the "Safety" is "On".
