Yes, but they still see what happens at Wrathgate. I mean maybe Tirion asks us to leave when the fight is over, but unless that happens I'm not sure why our characters wouldn't stick around to see what happens afterward, knowing what was told to them in the Halls of Reflection. Most of our characters strike me as the kind that like to make sure things get done.
I see your point. We know the context of the cut scene at Wrathgate. We don't see all the up-close-details of what happens from our perch, but we can put two and two together. Given the cut scene and the lack of context? At this point, for me, its speculation. I'm (hopefully) going to see that scene in game when the Sunday raid gets there. I do not want to see it BEFORE we get there.
Well yes, I'm not arguing that part. I just disagree that our characters aren't there when it happens.
Do we know exactly how this happens? Like you beat the Lich king and the cinematic plays? There is a huge difference of watching the cinematic in Dalaran and seeing it in the raid itself. I mean, if it is supposed to be secret, and we have this giant magical statue in Dalaran that plays the secret conversation between Bolvar and Tirion, someone in the Dalaran Public Works really screwed up.
Until I have evidence to the contrary, I'd have to agree with Threnn and Genise.
