The Last Night Part 4

Bobby knew for the moment that keeping Sam calm was the best thing he could do. Staring at the boy's tear filled eyes was tearing him up. "Sam, how are you feeling? Are you ok""

"M-my head hurts bad, and my neck. I-it hurts to move my head. M-my tummy feels weird . Am I ok, Bobby?" Sam speech was slow and stuttered. Bobby could see the pain in the kid's eyes. Sam looked like a lost kicked puppy.

"Sam, I think that is part of your head getting hit so hard. Let me buzz the nurse so they can get a look at you, ok?" Bobby was still processing the "new" Sam, who talks so slow, and so child like.

Bobby reached over to the bed's railing and buzzed the nurse. She told him that they would be there in a minute and alert Sam's doctor.

A couple of minutes later, Nurse Martin, who had been Sam's night nurse came in. She informed Bobby that Sam's doctor was still in the building and on her way in to see Sam.

"It is good to see you awake, Sam." Nurse Martin said as she approached his bed. "How are you feeling, Sam?"

"H-head hurts, lots." Sam managed to say.

"Oh, sweetie, I am sure it does, Doctor Morgan will be here soon, and she will take care of that for you, ok?" Nurse Martin said giving Sam's shoulder a soft squeeze.

Nurse Martin preceded to check Sam's pulse and other vitals, waiting for Dr. Morgan to arrive.

Dr. Morgan arrived shortly after Nurse Martin had finished up with checking Sam's vitals.

"Hello Sam, I am Dr. Morgan." Dr. Morgan, a woman in her late forties held out her hand to Sam.

"Hi" Sam answered slowly. He took her hand and she gave his a little squeeze.

"Sam, how are you feeling?" Dr. Morgan asked as she picked up his chart.

Sam sighed. "H-head hurts, and my tummy feels yucky."

"Dr. Morgan, Sam also mentioned his neck was bothering him, too." Bobby spoke up to the Doctor.

"Well, Sam that is to be expected and I will be giving you something to take care of all your pains ok? But first I want to do a few little tests, and see how your head is doing. Do you remember how you ended up here?" Dr. Morgan asked as she sat down at the edge of Sam's bed.

"My head got hit hard in jail, but Dean said I be ok. That I listen to you and Bobby and I be ok, right?" Sam answered as he looked at his hands that were nervously picking at the hospital sheet.

"That is right, Sam." She gave Sam's shoulder a little squeeze and turned towards Bobby. " Mr. Singer, do you think you could leave the room for a bit while I run a few tests on Sam? If you'll wait in the waiting room by the nurses station on this floor, I 'll come and talk to you when I am done with Sam, ok?" asked Dr. Morgan giving Bobby a reassuring smile.

"That's fine, I feel a bit in the way. I'll just grab a coffee and wait for you then." Bobby approached the Sam's bed and gave the boy a reassuring pat on the back. "Sam, I'll be back as soon as Doc here is done with you ok? Just listen to her, and you will be feeling better soon." Bobby was hoping a moment alone could help him wrap his mind around the reality of the "new version" of Sam.

"Ok, B-bobby, I will." Sam said. Bobby noticed that Sam definitely still had the kicked puppy expression down pat. Bobby gave the boy a wink and headed out the door.

Bobby had grabbed his cup of coffee and settled down in a seat in the waiting room. He was hoping that the Doctor would have some good news. Bobby was a man of action, and not being able to actually do anything to help Sam was driving him crazy.

Bobby was jerked out of a light nap, by the sound of his name being called out. "Sorry Doc, must have fell asleep to quiet here in this corner."

"I totally understand, it has been a long couple of days for you. I just finished checking Sam over, and he's doing pretty well considering his injuries." Dr. Morgan said with an encouraging smile.

"He definitely is suffering from many of the common TBI symptoms. Headaches and neck pain are very common. Slowness in his speech, and thinking, are also common, and Sam is definitely showing signs of these symptoms, as I am sure you noticed in talking to him." Bobby nodded and waited for her to continue.

"He also seems confused, seems to think that his brother is still alive. Confusion is also common, and as I mentioned before, I think we should wait until he is a bit better before we tell him about his brother and his legal situation. I 'm not sure that he would even understand any of that if we told him right now," the Doctor said with a compassionate smile. "We'll take things day by day with Sam, ok?"

"You're the Doc, Doc. You know what's best, and if thinking Dean is still with us for now will help, then that's what we should do. I just do not look forward to the day we have to tell him the truth." Bobby hoped that maybe Sam would regain his memory before he had to tell him.

"We gave him a mild sedative to help him sleep. He was already asleep when we left . So if you want to head out and get some sleep. He should not be up till morning." Dr. Morgan gave Bobby a compassionate l look, "You've been by Sam's side for the last 24 hours. You need to get some sleep."

Bobby grinned. "I think I might just do that, thank you Doc. "

"Goodnight, Mr. Singer, and if you need me to answer any questions, just have me paged, ok?" Dr. Morgan reached a hand out and gave Bobby's shoulder a reassuring pat.

"Thanks, nite Doc." Bobby rearranged his ball cap and headed to Sam's room.

Bobby poked his head in to Sam's room and when he saw that the boy was truly asleep, he headed out for the night.

Dean took this opportunity to sneak in and sit with his brother. Grabbing Sam's hand, he settled into the chair next to Sam's bed.

As the morning approached, Sam began to stir.

Sam's eyes fluttered open, as the sun light started peaking through the blinds of his room. He felt someone holding his hand and looked up to see Dean sitting in the chair next to his bed.

"D-dean?" Sam was hoping that he was not dreaming, that his Dean was back.

"In the flesh, Sammy. How you feeling, kiddo?" Dean said with a smile.

"Sun's bright, hurts my eyes." Sam pointed at the window.

"No worries kiddo, I'll just close the blinds, ok? Hold on." Dean hopped up to get the blinds.

"T-thanks, Dean, all better now. You take good care of me right?" Sam had a big grin on his face.

"You bet Sammy. I am glad you are feeling better. I told you the Doctor would give you some medicine that would make everything better, and I'm always right!" answered Dean with a smirk.

Sam nodded. " Doctor made it stop hurting. You right." Sam grabbed Dean's hand. "Can you stay today Dean?"

"I am so sorry kiddo, I can't. I need to leave before Bobby gets here. In fact, Sam, do you think that you could keep a secret?" Dean leaned into Sam like when they were kids sharing a secret.

Sam nodded, eyes big, and said " D-Dean, what secret?" The look on Sam's face reminded him of a six year old Sam who loved when his big brother shared secrets with him.

"Well, I think that it would be better if you didn't tell Bobby or anyone that I was here. That way if Agent Hendrickson, comes and asks Bobby or the doctor if anyone has seen me here, they don't have to lie, ok?"

Dean shot Sam and encouraging smile.

"Ok, I do that." Sam's face was so serious, it reminded Dean that his little brother can be a bit protective too when it came to his big brother.

"Good, Sam. You were so brave yesterday, and did a good job listening to Bobby and your Doctor, do you think you can do that again for me today? I need to leave, but I promise I will be back as soon as I can ok?"

Dean grabbed Sam's hand and gave it a squeeze.

Sam fought back the tears, and said, "I promise Dean."

"Good boy, bye Sammy. See ya soon, ok?" Dean hated the sad look in his brother's eyes.

"B-Bye Dean, love yoou." Sam said stifling a sob.

"Love you Sammy." Dean hugged Sam. Dean rose and gave Sam a wink as he walked out the door.

Dean wished he could just tell Sam the truth, but he had heard the doctor tell Bobby that Sam was not ready for the truth. Dean just took comfort in the fact that even as a spirit he could take care of his brother.
