Hey, at least we have a way to communicate with him.
Again, sort of.
Lets just get into this, shall we?

And this entire time, it seems hes been…sitting in a train station?
where he has been for a total of six hours, which isnt as long as I thought.
(Is time different in this dimension?)

Guess we know where Peters been!
Wait, lets back up… Thats when Peter quite literally walked free.
But he didnt get far before the Ghost Riders found him and shot him.
So now hes at this train station, where hes been for three months.
Just then, Peter realizes someone is watching them.
Turns out, not everyone here is catatonic.
Another outlaw claims the only way out is through the dark tunnel the Ghost Riders use.
At least we can check that off as a bad option.
With that, Peters ready to give up.
But who would ever come for you?
TAKE THAT, PETER.
Speaking of Stiles high-school sweethearts, theyre currently so, so close to remembering him.
Lydias not sure why, but she quickly heads outside to stop it.
It ends up costing her and Scott $150 what teen has that much cash on them?
but they manage to save Roscoe for another day.
Now, if only they knew why it was important.
Theyve been here before.
Furthermore, Lydia finds the deed to the car, which they trace back to the Stilinski household.
She then puts a halt on all of Lydias plans.
According to her, Lydia needs to let it go.
Instead, Lydia walks to the hallway where she once peeled back the wallpaper and cries.
As the camera zooms out… Shes sitting back to back with Stiles.
Just then, Peter looks at the board and notices something about the stops.
Sure, it might scorch him, but hes a werewolf, which means he will heal.
Dont get me wrong: Hes totally scorched.
But he still manages to roar through the pain, leading Scott and Malia right to him.
More importantly, Peter has something in his hand: Stiles keys!
And he gets through!
When Stiles asks Lydia if she remembers anything he said to her, she does.
You said, Remember I love you.'
YEAH HE DID, LYDIA.
Stiles tells them to find Canaan, a stop on the train-station board, before he loses the connection.
And then, hes gone again.
