From this post, Jimmy Smits character had a knife and stabbed someone (maybe they wanted the scene to be realistic so they stabbed for real).
But why did he have a knife? E! Online has revealed some possible plot spoilers.....
But why, oh why was Jimmy Smits wielding knives in what sounds like one of Dexter's kill rooms?
Well, I didn't want to spill this too soon and ruin the twist for anyone, but Dexter and Prado might just become murder buddies. This season was advertised as the year that "the student becomes the master," meaning that it's come time for Dexter to pass along his homicidal wisdom to an eager pupil...
I've known about the possibility of this tag-team effort for a while now, and I recently enticed Valerie Cruz, who plays Prado's wife, to talk about whether her character and Dexter's Rita (Julie Benz) ever get wise to their husbands' extracurricular activities. She told me, "The wives are so unaware that their husbands are murdering people! You forgive them because they obviously think that something's going on, but they try to liken it to what normal women would perceive: an affair or an addiction. So you never think, whoa, these girls are dum-dums!"
Valerie also told me, "[This season] so much becomes [known] about Dexter and Miguel. The rest falls by the wayside. What I think about the scripts this year is that there are so many stories going on and you think one story is going to break and be the story, but it's not. They were really smart this year—they gave themselves a lot of options."
What do you guys think about this turn? Post your thoughts on Dexter and Miguel's partnership in the comments along with your wishes for the cast and crew to finish out the season in a safe and totally uneventful manner!
