While the two of them are drunk out in the mountains, and on the phone with Mikoto, Miki starts groping Yuko, who only asks her to stop because in her own words "that's what I'm supposed to say right?", explaining that she and the men of Tobioka need to know if they're real.

* AnArmAndALeg: A Neo TV crewmember is shot in the leg by a terrorist when Wild Hunt invades the building.

* MortonsFork: The people with explosive vests strapped to them when Mikoto attempted to take down the remnants of the Kabuto-gumi. They are told that if they can kill Mikoto, the gang leader would let them live, but if they don't, he would set their vests off. Chikage tells them he probably wouldn't hold up that promise had they of succeeded. [[spoiler: It's defused when Oriha was able to disarm them.]]

* TheStinger: Several episodes end with one. Most of them involve [[BigBad Kaname Makiishi]], the leader of Syringe.
