It’s time to see what happened in this series through Matt’s eyes, in particular how he found out about Jackson being the weregecko and how he became its master
First of all, when Jackson borrowed the camera from him so he could film himself shift, Matt was in his car streaming the video (I do rather wonder WHY Matt was doing this) Jackson recorded. It was then he saw Jackson shift and had his first little binding moment through the car window, followed by the killing of Isaac Leahy’s father.
Stiles and Scott have the fun job of trying to convince Stiles’s dad that Matt is the actual killer, which he doesn’t buy it. Scott just assures him that he has to trust them (yeah, that works real well in criminal cases). The sheriff would really like to know if they have a motive for Matt to kill the swim team and its coach. Which they don’t have. They beg to see the evidence – but that’s in the police station where he doesn’t actually work any more. Stiles asks to be trusted – his father refuses, but he’s willing to trust Scott. Ouch, poor Stiles.
They check CCTV footage from the hospital where the pregnant woman was killed since it was the only time he killed someone himself, and they see Matt, albeit from the back which isn’t useful – but they do catch him talking to Scott’s mother – who does recognise him as Matt because she stopped him for tracking mud through the hospital. Which strikes another insight because they found muddy footprints at one of the scenes that they can try and match. And they had a receipt signed by Matt for an oil change at the garage where the mechanic was killed.
Apparently this constitutes enough evidence for a warrant. They call in Scott’s mother to get an official ID from her and Stiles runs to the front desk to tell the woman there to let her in. Except she’s dead – and Matt is there with a gun. Well you have some better evidence at least, guys!
He has the sheriff handcuffed to a pole and takes Scott and stiles on a police station tour of all the many many police officers he’s killed. Apparently the fun thing with being a weregecko master is that you just think about someone being killed and the gecko does it.
Meanwhile, last week we saw Derek being used by Lydia to raise Peter Hale, the last Alpha. This week he’s awakened from his gratuitous shirtlessness by Dr. Deaton using a dog whistle (hah) and letting him know that he fails as an Alpha – though he still is one. He finally tells us why he’s helping Derek so much, kind of anyway. Apparently advising the Hale family used to be an important part of his life, he promised Derek’s mother he’d look after him and he used to adviser Derek’s sister. And he has some advice for him – that he needs to not trust Hale even if he does offer him a deal to try and take down Gerard (hey, if it will kill an Argent, I’m all for team Hale!) and that he should be trusting Scott in helping him take down Gerard’s (that’s granddaddy Argent) master plan.
