At the end of your second faction mission for The Illuminati (You have to go to Shambala to retrieve an artifact of great power from a turncoat Templar) The Pyramidion reminds you he is not to be fucked with:
In the Dragon edition of the same mission, your contact casually mentions that they not only arranged the rogue agent's defection, but his career, his upbringing, his conception- even the fact that his parents met at all; the only reason why this guy was ever born was because the Dragon needed someone in the Templars to go renegade!
The into to "Revenge Best Served Hot." Bearing in mind that these next few lines come from two traumatized teenagers with no combat experience whatsoever, it becomes all the more awesome.
Aurelie: Werewolves, they are not an endangered species, are they?
Next mission intro, Celine is hacking incoming werewolves to bloody shreds, while Aurelie snipes the remaining few with a rifle- at one point casually nailing one of the sneakier ones right between the eyes. Once again, these aren't trained soldiers; they're stranded backpackers with no experience in combat or even the most basic knowledge of the secret world.
Carter finally getting the chance to cut loose with her powers in "Carter Unleashed." Watching familiars vanish in massive firestorms is impressive enough; the fact that this is an Escort Mission where the supposed damsel in distress is powerful enough to clear an entire room with one blast of magic just takes it to awesome new levels.
Montag admitting that he has firsthand knowledge of how to subdue a rampaging familiar- proving that he's Headmaster of Innsmouth for a damn good reason.
"A teacher is only as good as his tools!"
The intro to "From Carthage To Cairo." After being told that her deals with the Atenists will no longer be tolerated, Tanis pulls a gun on Säid. The mummy responds to this by sniffing the barrel and remarking that he smells gun oil, cheap perfume and desperation- before casually pushing the gun aside. For good measure, this actually pushes Tanis into frantically making counter-offers with all the wealth of the Phoenicians. Säid is not impressed.
In "The Prisoner," you're captured by the Atenists and your powers are temporarily disabled... thus giving you a chance to fight your way out bare-fisted!
Also in this level, the final beatdown you deliver to Saddur: after slugging him in the chops, kneeing him in the stomach, and headbutting him in the face, you kick him hard enough to impale him on a nearby pole!
