summary SPOILERS DO NOT READ IF YOU DONT WANT TO HAVE SOMETHIN RUINED
LONG but here- Matt holds scott,stiles and his dad in the station. Matt forces them to get rid of the evidence of him killing people. Dr.deaton is revealed to be a friend of the hale family and promised derek's mother to watch over derek and help him. Peter is back but not as strong+ derek is still the alpha. Its also revealed Matt is transforming into a kanima. Allison plans with Chris and Gerad to kill Derek. Matt proceeds to torment scott and the others until scott and the others are rescued by the argents trying to kill derek,jackson and matt. Its also revealed Scott is feeding Gerad info as part of his favor. Matt then flees the building while derek is fighting jackson and is killed by Gerad who then becomes jacksons new master. Scotts mom also finds out he's a werewolf. Peter is seen watching this then panics away
prediction- Gerad is going to try use his control over Jackson to kill scott and the others+ use allison to help accomplish it. I think Peter was going to use jackson to somehow get back his strength as an alpha. I have 2 theories on how 1. He was going to kill jackson and get his powers. 2. he was going to do what Matt was doing and by killing people himself become a kanima. I think this is more likely because Peter probably knows how to either control himself as a kanima or how to turn back into a werewolf.
I REALLY liked this episode it kept me on the edge of my seat of my couch the entire time, it had twists you didn't see coming,things like allison turning into a full blown hunter and scott's mom rejecting him as a werwolf were things you hoped wouldn't happened but they did.
hope you've enjoyed :)
