User blog comment:Le Rusecue/Did Dexter actually follow the Code in Season 5?/@comment-1846457-20110912161607

I was under the impression that he was going to kill the other four members of The Group because of Lumen. I think Dexter saw how Lumen had become "shattered" like he is. This created that bond between them and almost from the start Dexter showed affection towards here. I think in order to help her feel better Dexter agreed to help take down The Group. Plus I think that Dexter had a revelation that led him to think that the code Harry taught has now become his code, no his father's. Dexter I think feels he can alter his own code when ever he pleased as long as he keeps rule number one. Do not get caught.
