When you're down by the gate at Whiterun, Irileth is giving the pep talk to the guards before we head to the watchtower to fight the dragon, and one of the guards says, "We're so dead!"
Irileth: Listen up everyone, a DRAGON is attacking Whiterun tower!
Guards: What? wtf?! "Now we're in for it!"
Irilth: you heard right, I said a dragon! I don't really care where it came from nor who sent it! But what I know is that it has made a huge mistake in attacking Whiterun!
Guards: But housecarl? How can we fight a dragon!?
Irileth: Good question, none of us has ever seen a dragon, much less fight one. But we are honorbound to fight it, even if we fail! It is threatening our homes and families! Can you call yourselves Nords if you are to run from this monster? Are you going to let me face this thing alone?!
Guards: No housecarl! "We're so dead.."
Irileth: There is more than honor at stake here. Think about it, the first dragon ever seen since the last age.. And the glory to kill it is ours! Are you with me?! Now what do you say?! Shall we kill us a dragon!?
Guards: YEAAA!! "DAMN RIGHT!"
Irileth: Then let's move out.
I reworded the lines as to not y'know... yea. Anyway, was pretty close.
But yea, that's my one of my favorites. Sheogorath's quotes are funny too. I like them all. :3
