Yeah, the bank wouldn't let us move that fast, even if we wanted to xD One month before closing is pretty standard for them.

It would be. I could see Atlas giving that order before Cas has a chance to plead with him for her release.

And he really has. I could even see Ethan shooting him somewhere nonlethal, since he's got a gun.
When they get to the capital, it'll be the opposite, since Iris will be the prisoner that time.

I also had a thought. Maybe either instead of or in addition to Iris's ally, the military raids the prison? That could be a way for Cas and Iris to escape. They would slip out while everyone is running around, trying to fight or get away from the soldiers. The ally could unlock the cell for them during the commotion!
