Leonard came rushing back to Penny with bloody hands and knees, "Leonard what the hell?"

"Call 911. Ask for two ambulances and let the hospital prepare the massive transfusion protocol."

Penny nodded pulling out her phone with one hand. The other still cradled Amy's head on her lap.

"This is Dr. Hofstadter, I need two ambulances at 2311 Los Robles. Tell the hospital I need two rooms ready and the massive transfusion protocol in place." She put her phone back in her pocket, "Hang on sweetie" she whispered to Amy's unconscious form, "What's going on up there Leonard?!"

"His pulse is thready and weak, but it's there for now"

"Who's pulse"

"Sheldon's" he shouted back

Before she could ask anymore questions she heard the sound of sirens. One of the perks of living close to the hospital. She reluctantly let go of Amy to lead the paramedics to the right place. She ran back up the stairs with them right on her heels. One set continued up to where Leonard was with Sheldon, while she stayed with the other set near Amy. When they tried to move Amy onto the backboard, she started thrashing around. Her eyes shot open and Penny saw the fear in them. "Calm down Ames please. We're trying to help" But Amy kept moving and groaning.

"Doctor" one of the paramedics said, "we're going to have to sedate her. She just injuring herself more." She said lifting a needle out of her bag. Penny just nodded. She shifted out of the way when she heard footsteps approaching. She turned to see Sheldon's pale body on a board, with Leonard's jacket pressed into his abdomen, trying to stop whatever remaining blood. "Oh God Sheldon"

"We'll meet you at the hospital" Leonard said rushing down the stairs.

The ride to the hospital was tense and seemed so long to Penny, even though it was like 5 minutes away. She looked down at Amy, she looked so lifeless. She saw the doors of the ambulance open and Bernadette's face, "What happened?"

Penny jumped out, "No time to explain. Is Sheldon okay?"

"I don't know. Leonard rushed him to surgery."

Penny grabbed a trauma gown, "Get an IV in her. I need a head CT, I don't care if its busy she goes next." Penny shouted at a resident. She grabbed the portable ultrasound and moved the ultrasound transducer on Amy's stomach, "I see free fluid, could be blood. Get her to CT then meet me in OR 3." Penny said before rushing off to change. Bernadette ran after her, "Penny what's going on? Who beat Amy up? Why does she have so many bruises?"

"Now is not the time for questions Bernie. Just call Howard and Raj let them know what's going on. And call Sheldon's mother."

She entered the OR to see Dr. Patterson there already shaving part of Amy's head

"What are you doing?" she asked

"CT scan showed a brain bleed. You were taking too long."

Penny ran over to her friend, "scalpel" she said reaching out her hand.

"Bernie what's going on?" Howard said rushing towards his wife, "I don't know" she cried, "there was so much blood and so many bruises. I don't know who could do something like that."

"Do something like what?" Raj asked

"Somebody beat Amy up and tried to kill Sheldon." She said before sobbing into her husband's chest.

"What? Why? Where's Leonard and Penny?"

"In surgery with them" Howard led her to a bench to sit down. He clenched his fists, whoever that person was, they didn't know who they were messing with.

About an hour later, Penny came walking out of the OR, "How's Amy?" Raj asked

"Stable, she had some internal bleeding, but i fixed it. Patterson put her in an induced coma to give her brain time to heal. Did Leonard come out yet?" she asked

Howard shook his head, "I'm going to put Amy in her room. You guys can come"

They all sat in Amy's room with the monitors and clock being the only noise in the room, until Howard asked, "What happened Penny?"

Penny remained quiet, clutching Amy's hand.

"Penny. What happened?" Howard asked a little louder

"She was married, or still is. I don't know."

"Her husband did this?" Bernadette asked gesturing towards Amy, lying limp on the bed, bruises on her face and neck, a swollen eye and busted lip.

"How long?" Howard asked

"Almost their whole marriage, so like 13 years."

"No. How long have you known?"

"since the week she moved here"

"Why didn't you tell us? We could have helped."

"It wasn't my place!" Penny yelled

Leonard shuffled in the room at that time, "Sheldon's stable. He lost a lot of blood, but he's alive. How's Amy?"

"Induced coma" Raj said

Leonard ran a hand down his face, "What even happened?"

"Ask your wife. She knows everything" Howard said before walking out the room

Somebody knocked on the door, "Leonard and Penny, the police want to see you." Dr. Siebert said

"Doctors, we were told you guys were the first on the scene." one of the two officers

"We were the only ones on the scene" Penny snapped, "an apartment full of people and none of them came out."

"We understand your frustration"

"Do you? Do you really? Is that your best friend there in a coma? Was it your best friend that got stabbed by some psycho? No. So how could you possibly know!" Penny yelled before storming off.

"I'm sorry" Leonard said, "she's just a little emotional right now."

"That's alright. Can you tell us what happened?"

"I'm not too sure what happened, our friend asked us to come over and that's what we saw. There was nobody else there"

"Is it possible that they did this to each other?" the officer asked

"No. Never in a million years. They're not like that."

"Did you see anything at all? Anything that can help us?"

Leonard shook his head, "I'm sorry. But my friend has security cameras. We got robbed a few years ago and the landlord didn't want to put up cameras, so Sheldon had some installed around the apartment. There's one outside the door, maybe we could use that to see who it was."

"Lets go."

Leonard got a ride to the apartment because his car was still there. He led them to where Sheldon kept the security footage. He couldn't help but watch along with the officers. Watching the whole ordeal gave Leonard chills, he saw this strange guy force his way into Amy's apartment. He saw Sheldon go over twice. He could only see bits and pieces of the fight due to the camera's angle. After what seemed like forever, the strange guy finally came out the apartment dragging a fighting Amy with him. Leonard was glad there was no audio because he didn't think he could stand the sound of Amy's head hitting the stairs.

"Do you know who that man is?" the officer asked freezing the footage on the stranger's face

"I-I have no idea" Leonard answered.
