The Doctor's Angel

The Sound Of Drums/Swan Song

Note: A lot of this kind of assumes you have watched Supernatural. 

Merandria's breath quickened, panic rising in her chest. Everything was spiralling out of control. The apocalypse—something she'd always known was coming but hoped would never actually arrive—was here, and she was terrified. Angels weren't supposed to feel fear like this, but she did. Every fibre of her being trembled as chaos unfolded before her. And the Doctor... he had been missing since the encounter with the Weeping Angels. She couldn't sense him clearly, only a faint flicker in their connection that told her he was alive somewhere, but that was it. No location, no reassurance.

Her focus, for now, had to stay on the Winchesters. The Doctor would come back eventually, and when he did, she'd deal with it. But at the moment, her eyes were fixed on Adam, the half-brother of the Winchesters, taken as Michael's vessel, and Sam, who was preparing to say yes to Lucifer. She watched from the shadows as they tracked Lucifer to Detroit, holding onto the rings they had ripped from the Four Horsemen, their last hope to trap the Devil in his cage.

She clung to the fragile hope that maybe, just maybe, things could still go their way.

Castiel, her brother, moved with them, helping where he could. Merandria stood back, her black wings hidden in the unseen realms, watching as Sam drank the demon blood. Every second that passed, her dread deepened. She followed them silently as they finally confronted Lucifer. From a rooftop opposite the building where it all was about to happen, she kept her vigil.

Lucifer could sense her; she knew that much. His voice echoed in her mind, smooth and mocking: **"Little angel."** She could feel the weight of his dark amusement, knowing full well that she wouldn't dare interfere.

She watched as Sam spoke the words that would change everything: "Yes." The moment Lucifer took over Sam's body, she felt a jolt, like a rip through the very fabric of the universe. Lucifer smiled, triumphant, as he made his presence known in Sam's form, toying with Dean and their feeble plan with the Horsemen's rings. Merandria felt the crushing weight of defeat bear down on her, as if the sky itself was caving in. They were all doomed now.

Dean moved with desperation, grabbing the rings and chanting, but it was futile. Merandria knew the second the words left his lips that this would fail. Lucifer was too far ahead, too powerful. She watched in helpless agony as the brothers struggled to send him into the cage, their last hope slipping away with each second.

And then, Sam was gone. Lucifer had fully consumed him, and with it, any hope they had left. Dean collapsed in anguish, and Merandria felt a pang of sorrow in her chest. She had seen this coming but hadn't been able to prevent it. She watched as Castiel and Bobby stood by, powerless, just as she was.

She felt hollow, crushed under the weight of her own failure. Heaven had already been disappointed in her for losing the Doctor, and now she had failed again. The Apocalypse had begun in earnest, and she doubted that even the angels would survive what was to come.

With a trembling hand, she snapped her fingers and disappeared, not even knowing where to go. When she reappeared, it was in a dingy alleyway in London, far from where she intended to be. She blinked in confusion, frustration welling up inside her. She was supposed to follow Lucifer, not end up here. Her fingers twitched, ready to snap again, when a sound behind her made her freeze.

Three figures suddenly appeared out of nowhere. Her eyes widened as she turned to face them. Among them was the one person she never thought she'd see again: the Doctor. And beside him, Martha.

The shock of seeing him here, now, in the midst of the apocalypse, nearly knocked the breath from her lungs. After everything, after thinking she had lost him for good, here he was. She had failed to protect him, yet somehow, by some twist of fate, he was standing right in front of her.

**Brilliant timing**, she thought bitterly. 

"Time travel without a capsule—that's a killer. Owww," the Doctor groaned, wincing as he rubbed the back of his neck. Martha and Jack stood beside him, equally disoriented by their sudden arrival. They'd materialized in an alley, and the Doctor was clearly feeling the effects.
