This conflict is going to be over someday, and we'll need a way to "take care" of some of the loose ends on the Exile side. I know Silas would appreciate a clean, efficient means of disposing of his old enemy.

Funerals bells. My favorite flower. Silas gave them to me on our first date. Later, I held them when I married Hank. Then I used them to kill a politician.
