I am unconvinced that the master manipulator that is L'Rell has killed off Voq. She is the only one who knows this technique and the only one who actually knows what she did. I think it far more likely that she has suppressed Voq temporarily whilst reinforcing the commands that will bring him out again that didn't quite work before. I think he is still in there and the death roar was subterfuge.
I had missed some of the bonus content and am finally getting to your coverage of S1 ep1 Caretaker. I've really enjoyed it. I have seen the first 3 or 4 seasons back when they originally aired but haven't seen any since then. I can't say that Voyager stuck with me, it's my least favorite Trek. So my question for anyone is: What are the 5-10 best episodes of Voyager?
