After all, Crowley couldve put him back in the cage, but instead he decided he wanted revenge.
So when Crowley refuses to help, the Winchesters call in Rowena.
Their offer is simple: If she helps them locate Gavin, shell get to meet her grandson.
Rowena agrees, and a matter of hours later, Gavin gets off a bus in Iowa.
He says it was a gift he bought for his then-girlfriend, Fiona.
And considering that locket made its way into a teachers pocket yesterday, Sam and Dean better get moving.
That way, he can protect Fiona from the crew, and the two of them will die together.
Shell have no need for revenge.
This brings us to family issue No.
2: Crowley shows up in just enough time to stop his son.
It seems Gavin called his father, but it was only to say goodbye.
And when Crowley tries to use his powers to stop Gavin, Rowena shuts him down.
According to her, Gavin should get to do what he believes is right.
Spoiler: It works.
So now, she wanted to watch Crowley suffer the loss of a child.
After all, Im your mother, dear.
Who better to crush your shriveled heart?
She tells her sons that shes been working with the British Men of Letters.
Kelly then accepts Dagons protection so that she doesnt have to run anymore.
So this should be interesting.
As a whole, this was a solid case-of-the-week episode, and I enjoyed the added family drama.
