Derpy's Last Adventure

The Doctor quickly rushed out of the TARDIS and into a very large building. There was a sign with a red cross on it with the words "Hospital" written on it. He ran into the waiting room, while carrying Derpy on his back, up to the counter. There was a pink mare sitting behind the counter. She was wearing a nurse hat and had a gray mane color. The Doctor looked at the mare in the eye.

"I need you're best doctor. Right now." He said.

The pony rolled her eyes and gave him an angry look. She moved her head towards him and spoke to him in a mad tone.

"There are other ponies who are waiting. You must wait like them." She said as she pointed her hoof towards the ponies sitting in the waiting room.

The Doctor moved his head forward, putting his face against the mare's face. He had an angry look on his face and he WAS going to get a Doctor.

"This mare here, is dying. She needs the best Doctor that you have her. She was bitten by a venomous changeling. She needs help NOW!" He exclaimed, nodding his head toward Derpy.

The mare's eyes widened. She realized what was going on. She moved out from behind the counter and walked up to The Doctor.

"Come with me, and hurry." She said as she started to rush down the hallways of the hospital.

The Doctor followed her, trying to keep up. She was a fast mare, that was for sure. The Doctor tried to keep up with her, without dropping Derpy from his back. They passed by many rooms, doctors, nurses, patients, and other Hospital staff. They all looked at The Doctor and Derpy with sad eyes and their heads hung low. They all knew what was going on. The mare stepped into a room and motioned for The Doctor to come in. He walked into the hospital room, finding a bed, a heart monitor, and a yellow stallion in a white coat. He looked at the mare with a confused look.

"Who is this?" The stallion asked.

The mare looked at the station with sad eyes.

"This is-" She started.

"I'm The Doctor." The Doctor cut in. "This mare is dying. She needs medical attention immediately!' He said in a serious tone.

The stallion took Derpy off of The Doctor's back and laid her on the bed. He turned on the heart monitor, and it started it's normal beeping sound. He turned to The Doctor.

"I'm Doctor Storm, by the way." He said, introducing himself.

The Doctor nodded, acknowledging him. He walked next to the bed, looking down at Derpy and the wound on her heart. He noticed a bit of movement from her. He started to realize she was waking up. Her eyes open, derped as always, and her eyes darted around the room.

"D-Doctor? Wh-what's going on? Why am I here?" She asked, clueless to what was going on in the hospital.

The Doctor looked at her and his head went down.

"D-Derpy... You were bitten by a ch-changeling... A venomous changeling..." The Doctor responded, tears falling down his cheek.

She looked down at the wound on her heart. She then remembered. The changeling, the fight, the tree, the fall. Everything came back to her memory. She knew what was going to happen. Either a life would be saved, or a life would be lost...
