Blood+ Episode 19

Episode title: 折れたココロ (Oreta Kokoro: Shattered Heart)

"Liza" works her way into causing doubt in Saya's resolve, Riku falls ill, and Liza shows her true color and a battle ensues. Pics (click to enlarge) and detailed summary below:
The show stars with cloaked yokushuu preying on a young woman. There are three of them and they talk about catching up soon to kill their prey, Saya. Then the opening song starts (you can see the same cloaked yokushuu in the opening animation... there are at least 9 of them). The episode continues with Saya and folks checking into their hotel and they take a bath. While Saya's taking a shower, she talks to herself about the dreams she's had. Liza's in the bathroom, saying she had forgotten something, and asks Saya about her dreams. Saya talks about her dreams of being with Haji before in Russia and her dark dreams about killing people in Vietnam. Liza says softly that her past is surfacing. Meanwhile, David & folks are driving back to the hotel. Julia comments that David is softening (talking about Kai). She said before he was like a robot, but now he's more like a cyborg or android ^_^. David comments it seems he's become weaker. Julia says she likes him better this way and that people can't live only by strength alone.Meanwhile, Saya & company are eating, but Liza doesn't eat; she uses the topic to associate humans to yokushuu; they both kill and consume other living creatures to survive. She also asks Saya if she's ever thought about what yokushuu are really or why they exists. Saya admits she knows nothing about them, but she has to kill them to protect others. Liza says it may be Saya's duty to defeat yokushuu, but is it something that she truly wants to do from the bottom of her heart? Liza implies that there instead of trying to mix her duty with what she wants to do, there is something else that she truly has to do. However, at that moment Riku collapses; he has a high fever. As Saya's breaking apart ice for Riku, Liza continues to bait and dig her claws into Saya's heart. Finally, by Riku's bedside, Saya finally asks her what she's trying to get at. Liza talks about how everyone is keeping secrets from her. Saya replies that she's been told that those are memories that she needs to remember herself. But Liza reminds her only of the battles and the blood. Saya collapses to the ground, in pain from the death of people at her hands. At that point, Haji blasts through the room, both attacking Liza and protecting Saya. They finally realize that Liza is not Liza and she admits to sucking out the real Liza's blood and killing her. She finally shows her fangs. Haji gets blasted from the room and falls several stories to the snow. Liza flies and lands/knees Haji, nearly breaking his spine in half. Saya jumps down with her sword. Liza points out that Saya is not human and that her "family" is not her true family. She said that it's stupid for her to fight on the behalf of humanity... after all, Saya's related to them... that she's a yokushuu herself. Saya reels from these words. Liza even accuses Haji of hiding these truths from her. Haji tries to attack her, but Liza easily evades his attacks and rips a hole through his chest.
Saya's eyes finally turn red and she attacks with her blood sword. However, Liza easily evades her attack as well, grabs her sword, then says, "playtime is over." She lets out a subsonic howl and the snow erupts around Saya and her sword breaks in half. Then Liza appears behind her and whispers even more terrible words: Saya has real family... her younger sister, Diva. Saya's been ordered to kill her own sister by Red Shield. And worse, everyone knows except Saya herself. Liza says if she wants to know even more, then to come to the zoo where it all started. Then Liza senses others; the three cowled mystery yokushuu are watching from the woods. "Aren't we going after her? Our enemy is before our eyes," says one. "Yes, but that chevalier is there." They retreat. Liza, in a male's voice, smirks and comments, "So, it's the Shifu (I think that's what he said... not sure). Interesting. The hidden world is leaping in blood (or something like that... my Japanese is not good enough to figure this out clearly)." Liza returns his/her attention to Saya and tells her farewell, that it was fun, then he/she disappears.Back at the hotel, Kai and Julia are by Riku's bedside. David and Lewis enter the room; David has Saya's broken sword and a note Saya has left in the next room. The note is simple: it reads, "Liar." Meanwhile, on a U.S. carrier we see the open container that was housing Diva. The doors are broken open and blood is dripping from within. We see a naked girl's foot begin to step out. End of episode.

Loved this episode. More of Saya's past is revealed and we see Diva emerging. Diva's chevalier (or whoever "Liza" really is) is really strong. And the cloaked dudes make their appearance too... I wonder what relation they have with Diva & her chevaliers.
