So what happens when hes not only taken but erased from existence?
Thats the question this season will have to answer after that emotional premiere.
Talk about setting the mood!

Their latest heroic act?
Crashing a van full of stolen helium.
So yeah, maybe Beacon Hills doesnt need them anymore?

However, as soon as Scott leaves Alexs mind, he cant remember everything he saw.
The only thing thats certain at this point is that the Ghost Riders will be back for Alex.
More importantly, Scotts not convinced this case is even supernatural.
Its been three months since anything happened in Beacon Hills, and it has Stiles going a little crazy.
In typical Stiles fashion, hes been claiming that everything is supernatural lately.
But he might be right on this one.
Well, thats IF he can get past Mrs. Martin.
It leads them straight to Alexs house, where Scott and Stiles are currently snooping around.
Stiles stays behind after Scott leaves the room to check out the photos, but that leaves him vulnerable.
When the Ghost Rider shows up, Stiles is the only one there to see him.
The bad news is that Stiles saw him.
And as soon as the Rider leaves, Alexs room is erased.
NEXT: Remember I love you
Back at the school, Lydia and Stiles realize whats happening.
Stiles takes that information straight to Scott, whos leaving lacrosse practice, which no one told Stiles about.
Also, why is some kid wearing Stiles jersey?
Yep, this isnt good.
Furthermore, no one even remembers him coming in.
But they havent figured that out yet.
And heres where things really start to go south.
Just like that, everyone starts to forget Stiles.
First, Mrs. Martin doesnt recognize him.
Then its Liam, Mason, and Hayden acting like Stiles doesnt even go to their school.
And then, worst of all, Stilinski doesnt know his own son.
Stiles calls Scott in a panic, only to hear his best friend ask him, Whos this?
Just as she promises not to leave him, the Ghost Riders arrive.
Then we get this:
Stiles:Youre gonna forget me.
Lydia:I wont.
Stiles:You will.
Stiles tells Lydia to find some way to remember him.
Then, Stydia fans get the moment theyve waited for since season 1.
Shes the girl who saved his life (and he saved hers).
Most importantly, just remember … remember I love you Stiles says seconds before hes taken.
Ive watched this moment multiple times now and it always gives me chills.
He finally said it, and it couldnt have been a more perfect goodbye.
The next day, Lydia shows up at school feeling like she was supposed to do something.
But she cant remember what.
Altogether, I really enjoyed this hour.
