It was already going downhill when the demons showed up.

U. M. threw a couple punches at one before ducking out of the way. Cass backed up slowly before stabbing one with his angel blade. Dean and Sam were working with Holy Water and the knife.

"Give me some of that," U. M. finally said, taking a bottle of holy water from Sam. She flung it at the demons, controlling its path and splattering all of them. Despite the angel, goddess, and hunters' best efforts they were eventually bullied out onto the beach.

"They're trying to open this seal," Dean realized, stabbing another one. Finally, outnumbered, the group stood at the water's edge.

Then the angels came.

So it was angel against demon and somewhere in the mess U. M., a demon, and Castiel got herded out into the ocean and were dueling it out. It was going fine until the demon got stabbed and then blades came at Castiel and U. M.

U. M. twirled her fingers like she was twirling a baton and a double bladed poleaxe came into view. She blocked the blades and circled around Cass waiting until the boys finished an exorcism that sent all the demons away.

"That was a close one," U. M. smiled tersely. "Any of you like to come in for tea?"

"Wait, just what are you?" one angel asked.

"The sun and moon's glorious union," she replied coolly, heading toward the house and pulling Cass along. "Your seal. Now if you excuse me we need new clothing." When they entered the house she said slyly to Cass, "I better have some cred now that I saved your life there."

"I could have defended myself," the angel tried to defend.

"Not against other angels." He blinked.

"What do you know?"

"Nothing darling." She smiled at him and Sam and Dean came in.

"Well the angels left," Dean said.

"Good," U. M. commented, heading up the stairs with Cass. "Now let's get you some dry clothes honey."

They came back down in pajamas, Cass in what was probably Dean's pajamas, and all of them sat on the couch in silence.

Finally Sam broke the ice, "Why were those angels trying to kill you two too?"

"I don't know Sammy," U. M. lied.
