Broken Pedestal: Millerna's faith in her Father is shattered by his turning a blind eye to Zaibach's impending invasion of Freid (thereby sacrificing his own grandson to protect Asturia). Allen's own loyalty and oath to his monarch (which had already taken a blow during Episodes 6-7) is further damaged upon learning this.
Chekhov's Gun: Hitomi's pager, which Merele steals early in the episode, ends up providing a crucial distraction after they're captured.
Properly Paranoid: King Aston detains Allen partly because he aided and abetted Van's flight from Palas, but also to prevent Allen from trying to stop and sabotage Zaibach's invasion of Freid.
Wham Shot: Van has angelic wings, revealing he's the angel Hitomi has seen in her visions.
Victoria's Secret Compartment: How and where Merle stores all the stuff she stole from Hitomi's gym bag. Ironically, it ends up being important for triggering the previously mentioned Chekhov's Gun.
