You call for help, thats what.
(Reminder: They need Gabriels grace to make it get back to the Apocalypse World.)
But lets just say that doesnt go as planned.

And you know what?
They might be willing to help.
But first, Castiel has to have a conversation with…NAOMI!
Shes back (with some awesome short blond hair)!
As she tells Castiel, a drill in the head was never going to kill her.
She just needed some time to recover and put all of her thoughts back in her skull.
Shes still not 100 percent, but at this point, she doesnt have a choice.
Those flickering lights in heaven?
(Alternate title option for this episode: Heavens 11.)
Naomi explains that thats why none of the angels can leave heaven to help him find Gabriel.
In other words, the Winchesters workload would double.
As she tells him, Everything ends.
(Clearly she doesnt watchSupernatural.)
By killing people, Rowena is causing people to die before their assigned times.
But wait, its actually more than that.
Shes also killing reapers.
Only, Billie isnt one for bargaining…and she HATES blackmail.
Shes not interested in bringing Crowley back, and if that means that Rowena kills Sam, then fine.
But Rowena doesnt kill Sam.
Instead, she turns her powers on Billie.
Spoiler: Billies not affected.
After Billie tells Dean that shell see him again soon WHAT DOES THAT MEAN?!
she heads out, leaving Sam and Dean to ask Rowena for help finding Gabriel.
But Sam would like to think that, if they work together, they can change Rowenas fate.
So, is she in?
Well have to wait and see.
