Hey, I also found this scene very suss and want to talk about it. Lowell had already accepted he was going to die, and was really chill about it. Totally accepted it. Then, when Dexter reveals hes not red, but the BHB, Lowell suddenly panics. His final words are youyou Dexter pays it no mind. Im sure most of the audience didnt either. But to me, it looked like he had something important to say before he died. Im guessing the BHB is special and held in a different regard to the group, and this was some foreshadowing. Maybe theres a personal vendetta? BHB butcher killed someone related to or close to the group? Or maybe the BHB is like the White Whale Prater has been after, believing he still lives and is one of the most prolific serial killers of them all.
