Either way, lets get to it.
Im breaking down this episode into three story lines.
If she mixes them incorrectly, she kills him.

And yet, she doesnt kill him.
Instead, Melissa saves the day and all is well with my favorite non-love story.
And its not just any ghost town.
And according to Lenore, no one else will ever leave… Scott, Malia, and Lydia included.
I told you guys: horror movie.
If Lenore somehow got the Ghost Riders to resurrect her son, that means she can communicate with them …
It also means Lydia could end up being the only person left behind in Beacon Hills.
Lydia asks Lenore to help her.
Dont let me be the only one left behind, she begs.
I dont have a Caleb.
With that, Lenore and Caleb let the three of them go.
As for why Stiles sent them there, Scott thinks it was a warning.
If theyre not careful, Beacon Hills could become the next ghost town.
They become Ghost Riders.
Translation: If the Ghost Riders leave Beacon Hills, Stiles precious face suddenly wont look so precious.
They need something that can absorb the energy of a lightning bolt.
The bad news is that Theos brief trip below ground has stripped him of anyone elses powers.
Hes back to being classic Theo.
And thats where the episode ends.
But as for all the Canaan stuff, I wouldnt have minded if it were a bit shorter.
Or maybe thats just my phobia of creepy children.
