Dexter is tempted into an ambush. Quinn puts his private feelings about Dexter aside in order to ask for his help. Deb allows her emotions cloud her decision.
The short one says that Dexter realizes he is being attracted into a trap; Debra lets her personal feelings overwhelm her instincts; Quinn needs Dexter’s help.
First of all Dexter is heading to save Lumen and judging from his look from the end of the last episode, it is going to get horrible.
Although knowing he's being tempted into a trap, Dexter risks everything to make sure he doesn't fall into the same mistake again. In the Barrel Girls case, Debra lets her personal feelings lead her instincts once she concludes that vigilantes are more than just a theory. Quinn finds himself in a troublesome situation, which only Dexter can help him out of.
By now Dexter relationship with Lumen had a pretty slow paste but in the last two episodes, spatially the last one it evolved to the point where Dexter seam to be truly in love with Lumen but she is much more to Dexter then any women has been so far in his life-she is his partner , the only person who understands him and truly knows him, even when Dexter was talking to little Harrison about his dad being a killer he said numerous times that he won’t be able to do that much longer as he will soon understand what he is saying.
Dexter is in rage or better yet, he has reached the boiling point of rage which has been growing throughout Dexter season 5 and we can surly state that we havent seen anything from the Dexters neat monster in season 5-he has been everything but neat -he was reckless all the time and now in Dexter Season 5 Episode 12 he will be truly out of control.
Quin really got himself in a bad situation with Liddy he tried to get out of but unfortunately for him I highly doubt it will go well except Dexter somehow helps him -preview almost states that Quin needs Dexters help and we all know what a mistake on Dexters part was not to take those pictures of him and Lumen from Quin’s apartment while he had a chance.
