Well my wishes for this show were kind of answered.
I ultimately hope that one day she accepts him rather than understand him, and lets him do the killings. But I have a feeling that the more files Dexter looks up from the archives, and tells her sister about it; she'll learn to accept what he does. She just understands it, which I could argue, is the same thing as accepting, but not quite...
I hope she helps him out one day. She can look for his targets, provided he shows her the proof and Dexter does the rest. But now it's really interesting because Ray Winstone's character might uncover Dexter's identity..and Dexter is not trained to deal with the Mafia, but the police is, so his sister will have to do the protecting this time around.
Also, who got a hard-on when Miranda Lawson yeah I know it's not her real name, but that's how I remember her by, from Mass Effect) walked on-screen with those sexy booty shorts and when she opened her mouth for a cotton swab...I kept shouting, "Dexter, get on that!
