As we play through the story, Braham correctly senses two powerful destroyer minions before they appear, this is so strange that the commander asks him about it after Metrica Province is saved, and while Braham said he didn't know, I began developing a theory. DISCLAIMER: I don't think this is actually gonna happen, I just think it'd be pretty cool to think about. What if Braham is going to become Primordus' champion? Think about it, as I said before he can already seem to sense them for some reason (though I do realize it probably has nothing to do with Primo himself) this could be considered a connection. Braham is also confirmed to be the norn of prophecy where him and Jormag are to kill one another, wouldn't it be poetic justice that the champion of Primordus is the one to fell the ice dragon? It's also pretty clear that Braham is obsessed with taking down Jormag (rightfully so I might add). He's also shown to go off the deep end before, after Eir died he became almost hateful of the commander and went against his friends, what if he does so again? And for the thing that made me think this could actually happen, is the title of the episode, "Champions". Right now it seems odd to call it Champions if they are only two at the moment, being Ryland and the Commander, the title makes much more sense if there's a third one, Primordus'. Final note: Braham becoming the fire dragon's champion would destroy our spirits, and what is Primordus, if not the dragon of destruction? Just food for thought, once again I don't think Anet would actually do this, but I think it'd be incredible if they did.
TL;DR Braham could be on his way to becoming the fire dragon's champion
