Another somewhat strange thing is that Hobbes, who was “too valuable” and a superstar on WC2, was relegated to an old, not so important carrier on WC3.
Perhaps this was *because* he's too valuable, though. The Victory, assigned less important missions (before Tolwyn's adoption), is a nice mix of the combat role he insisted on in Wing Commander 2 and a safer assignment preferred by High Command.
The bigger question is: what happened between End Run and Wing Commander III? Ralgha went from being the Wing Commander aboard the flagship of the Confederation's most important fighting fleet to being Executive Officer of the Victory in the space of two years. Even his initial assignment, temporary Wing Commander/permanent Executive Officer for the 58th Fighter Wing is a heck of a step down in both position and prestige.
I'll end by noting that Wing Commander 3 makes a point of saying that the assignment as Eisen's exec was *Ralgha's* decision. Foreshadowing that implies some level of Kilrathi control over him at the start of the game or simple coincidence?
I understand Tolwyn’s rather brilliant allocation of resources with the Behemoth in mind (and, eventually, the T-Bomb), but what role would Hobbes take in this plan?
I believe Hobbes is one of the specific example Kevin cites regarding the choice of the Victory - while other carriers may be more polished, the Victory has a 'genuine expert on Kilrathi psycology' (and for better or for worse, this isn't something Tolwyn necessarily came up with... Eisen is clearly using Hobbes to help him predict what the Kilrathi will do earlier on in the story).
Also, as to where homeweorld comes in, Wasn't rhalga and the priestess who coverted, to tell him to go the humans(or possibly implanted the memory in his head regarding the chapter in the WC2 manual) in the betrayal born on another planet than kilrah?
It's hard to know for sure. Freedom Flight says: "[Ghorah Khar] reminded him of home, of his native planet of Hhallas, where he had lived his childhood, before spending his years in officer's training on Kilrah. Many Kilrathi said they admired the metallic splendor of Kilrah, the silver walls and tall towers of the Imperial planet. Not Ralgha... even after all these years he still yearned for the wild mountains and untamed wilderness of his home planet."
... but then the Victory Streak character stats accompanying his letter say: "Homeworld: Kilrah, Hhallas clan". It also seems clear that his line about "returning to my homeworld" in Wing Commander III refers to Kilrah rather than Hhallas (though the latter would be so much more romantic). The Heart of the Tiger novelization also notes that Hobbes kept his quarters lighted with a "dim reddish hue," which was "a reminder of Kilrah's K6 star. A reminder of Ralgha's home...".
