Dexter season 7 will introduce Chuck actress, Yvonne Strahovski this fall. TV Overmind got us an in-depth first look to Yvonne's character as a hortacologist which will emerge on season 7 episode 3 entitled, "Buck The System".
- Hannah does indeed have a connection to a significant event that occurs in Dexter's presence during Season 7, and her connection to someone Dexter runs into and their background suggests she may yet have some history with Dexter. And perhaps even beyond, perhaps even on the Rita level.
- Like many things in Dexter Season 7, Hannah's ultimate purpose seems to be something the writers are content unreeling slowly. By the end of 7.03, you will NOT know even how she could possibly recur, that is how tangential her first appearance seems. But keep an eye out for subtle clues that may or may not indicate a connection with Dexter. In a few words: Ice cream.
