Ep 10. Road Trip

Sam and Dean are on the outs after Sam's disastrous attempt to close the gates of Hell and Dean's refusal to forgive him for it. Dean seeks out Crowley for help in finding the fallen angel, Gadreel, who had been possessing Sam and caused so much damage. Crowley agrees to help, on the condition that Dean kill Abaddon, the last remaining Knight of Hell, and hand over the First Blade, the only weapon that can kill her.

Meanwhile, Castiel is struggling with his own issues, having lost most of his grace and becoming human. He is befriended by a bartender named April who becomes embroiled in a demonic plot to open a portal to Hell and unleash an army of demons on Earth.

As the three individual storylines collide, tensions rise and loyalties are tested. The episode is a rollercoaster ride of action, betrayal, and emotional moments as the characters attempt to find redemption and save the world from yet another apocalyptic threat.
