Things are looking increasingly dark for Stiles, Lydia is overwhelmed by her abilities, Derek continues to mentor Scott, Allison gets a surprise, and we meet a new kitsune....
So, Mrs. Yukimura is also a kitsune. There is no way that their move to Beacon Hills was in any way, shape, or form a coincidence. There is no doubt that Kira's family knew what was going on and moved to Beacon Hills in order to stop the nogitsune. It was also interesting to discover that she also apparently controls the oni. Or at the very least, they are working towards the same goal because they came to her when she confronted posessedStiles (I'll go with Piles for now). I am afraid we are going to see what happens when an unstoppable force meets an immovable object and the consequences for Beacon Hills will be grave indeed. Mrs. Yukimura is willing to sacrifice Stiles in order to kill the nogitsune even though he is an innocent. This last will definitely bring her into conflict with Scott.
Scott, as has been well established and I have commented on repeatedly, is constitutionally incapable of sacrificing a friend, even if doing so would serve the greater good. Thus far, he has managed to get around any obstacle in his path by coming up with a creative plan, but I don't know if that will work here. Since the nogitsune is possessing Stiles, it may also have access to his memories. If it does then it will probably be able to guess at what Scott will do and come up with some sort of counter. He is going to have to use Kira (and maybe her mom) as a part of his plan, but I don't see how. It is possible that Kira could somehow harness her electrical energy and kill Stiles with it; thus causing the nogitsune to leave him; and then bring him back, but I don't know if that will actually work.
Derek's explanation of his family's presence in Beacon Hills was quite interesting and makes a great deal of sense. Since Beacon Hills is a convergence point for natural and supernatural energy, it makes sense that guardians would be put in place in order to protect it. The Hale line seems to be an immensely powerful werewolf line, so having them there to protect Beacon Hills makes sense. This could also explain why a True Alpha is living in Beacon Hills. Deaton said that a True Alpha is the result of a pure spirit and immense willpower, but I wonder if there is a third condition, namely enough supernatural energy to help jumpstart the process. Again, it would make sense. A True Alpha is the strongest type of Alpha and also the best and purest type of Alpha, thus making the True Alpha the perfect guardian for a convergence of supernatural energy. To draw an analogy, think of why a Slayer would be drawn to the Hellmouth in Buffy the Vampire Slayer or why a family of powerful good witches would guard a Nexus in Charmed. Same basic idea. Immense power requires a powerful and good guardian lest the power fall into the wrong hands.
I am worried for Stiles and Allison. Allison is starting to lose time, which makes me wonder if maybe she too is being influenced or possessed by the nogitsune. If so, Scott will potentially have a horrible choice on his hands. He may be forced to sacrifice either his best friend or the girl he is in love with. Not a pretty choice either way. While I am glad that Stiles is fighting back against the nogitsune, I don't think he can last much longer. I also wonder if the atrophying of the brain noted in the MRI is a result of the nogitsune in Stiles or if he really is experiencing dementia. Again, neither can be good for him.
Lydia is having more and more trouble controlling her abilities. Her hearing is starting to overwhelm her and she seems to be having trouble distinguishing between who she is being drawn to. I am willing to bet that the basement of the mental hospital has a connection to Barrow and that because Barrow is connected to Stiles being possessed by the nogitsune, she led everyone to the basement. I am not sure how she is going to get a handle on everything, but she has to because she is a very useful part of the team.
Until next week!
