Although I think that Hobbes' feelings should still have been brought out to the audience a little more openly. The cut "message from Hobbes" would have been very helpful (why would they cut a scene like that?), and it would have been nice if Hobbes and Blair exchanged words over Kilrah.
Ok, for the record - I do agree that the 'trigger' thing was poorly done. It's something they went through a lot of effort to set up... and apparently, ultimately felt it added so little to the game, that they chose to cut this particular scene instead of one of the others. Which was the right choice - all things considered, the 'trigger' raises many more questions than it answers (for example - why did the Kilrathi only start not-trying-to-kill Hobbes in WC3? And how come Confed Intel never heard anything about an order apparently issued to all Kilrathi pilots, to not shoot at Hobbes?).
However, that having been said, I think the lack of words at their last meeting is very appropriate (and it's even appropriate that Hobbes has something to say if you pursue him right away, and has nothing to say if you don't).
The really, really great thing is that you can read a lot into Hobbes' behaviour. As you say, the silence may mean that Hobbes is truly gone, and replaced by Ralgha. It may also mean the exact opposite thing - that there is so much of Hobbes left, that Ralgha is afraid to get into a conversation with Blair. Heck, Ralgha may even feel that the Confederation is the
right side in the war, and may be cheering Blair on - while at the same time, remaining faithful to his side. I'm not saying this is the case, I'm saying it could be. It's a situation that would be consistent, not only with what little we know of Kilrathi honour, but also with our own medieval history. As a general rule, people who committed treason for money or similar vile reasons, when caught, were willing to say anything to weasel their way out. But people who committed treason because they felt it was their duty - very often, they really couldn't face their (former) friends afterwards, they really couldn't say anything to them. Not because they weren't sorry, but because, in some way, it was wrong for them to be sorry.
Anyway... there are many explanations that can work if Hobbes remained silent. Had he opened his mouth, he would have forced us to go with one explanation. It would be much more straight-forward, and and it would not be doing justice to a very, very complex character.
I personally,
love the idea that there he was, defending Kilrah against Blair, all the while thinking (based on his experience as Hobbes) that Confed
should win, and hoping that Blair
would win - but, remaining true to his honour, refusing to step aside or to let Blair kill him without a fight. It's fantastic, tragic, and strikes me as an appropriate mix of human and Kilrathi honour and logic.
I guess it may be that I like his silence in this scene precisely because I know this is not the explanation we would have heard had he spoken - more likely, it would have been a very cliche message like "you were my friend, but I have to kill you now because I am a true Kilrathi" or something like that. In other words, we would have heard that Ralgha has all of Hobbes' memory, and even some of his feelings, but that his thinking processes are entirely unaffected by it all. No, on this particular plot point, I prefer to have doubt rather than clarity.
(besides, ultimately, Ralgha himself said it best - "no one will ever truly understand me" - what cutscene could possibly give you the kind of narrative closure you're looking for?)
Also, the metaphor idea - I don't like it. The three points you make have nothing to do with the idea of a metaphor, both because they are inaccurate, and because they'd still be incorrect even if they were accurate.
- Wing Commander games are not all about two enemies being accused of treason, but in fact being loyal. Blair's story is just something that happens in
one of the three Kilrathi War games. And Hobbes' story is entirely different in any case - where Blair is falsely accused, Hobbes
does commit treason. And then Ralgha does, too. After all, even if Hobbes was a false identity, he did still break his oath to the Kilrathi. And Ralgha too, flies on your wing and then betrays you. So, no metaphor here.
- Duty is not a subject that takes up much space in Wing Commander games (and, though irrelevant here, it's worth noting that WC4 would go on to make the opposite message - that personal feelings can be enough to justify treason). In WC1 and WC3, Blair fights the Kilrathi because it's only way to survive the war - and in WC2, he seems to fight them more because of personal feelings (he wants to prove that he's not a traitor) than because it's his duty. So again, in this aspect there is no metaphor.
- And finally, it never did come down to one final duel. In fact, WC1 entirely skipped the final duel thing (for reasons unknown, while all surviving Kilrathi aces show up to fight you in the final losing path mission, none of them show up to fight you in the final winning path mission), while in WC2 and WC3, confronting Prince Thrakhath seems to be incidental rather than crucial. WC3 in particular, seems to go against the original game. Where Claw Marks told you to focus on your mission objective, and WC1 itself allowed you to use tricks of navigation to skip encounters along the way and only take out the final objective, WC3 tells you that Blair must de-cloak (thus blow his cover and risk total mission failure) just to get one final shot at Thrakhath. Ironically, this means that in trying to avenge Angel, Blair does something that she would have been hugely angry about. And Angel is the character that WC1 told you to be like - a professional, who goes by the book not because it's her duty, but because it works and gets the job done. In any case, duels are not what Wing Commander games are about - duels are something that got tacked on in WC2 and WC3 (...and then in WC4) for dramatic purposes. So, no metaphor here, too - although this point came closer than either of the others.
