"Daleks!" Sherlock thinks, he has been traveling with the doctor for about 2 years on earth terms and has encountered his fair share of Daleks. Sherlock does not know all that much about them except that they hate the doctor and kill everything in sight. Daleks he knows how to work with, Angels and Vasta Nerada are much more difficult, stones that move when you blink, shadows that melt off flesh, with Daleks you shoot them in the eye stalk and they die.
Amelia-Rose and Sherlock run, a Dalek close behind. The two run into a a dead end, and are forced fight. The Dalek catches up as Sherlock reaches for the blaster in his coat pocket. The Dalek shoots and hit Amelia-Rose, as Amelia-Rose starts to re generate another Dalek hits her again. When they are getting ready to attack again Sherlock kneels down to Amelia-Rose and listen for a heart beat, instead he find silence. He grabs his blaster and aims it for the Dalek, "you just killed the woman I love!" He yells as he pull the trigger and the Daleks are shot dead.
The Doctor and River run to find the 2 and come across Sherlock weeping. "Sherlock," The Doctor approachs "what happened?"
"It's Amelia-Rose, a Dalek shot her." Sherlock replies between tears.
The Doctor runs to Amelia-Rose and scans her, "You couldn't have protected her! She trusted you totally and this is how you protect her!" The Doctor booms.
"Sweetie, I am sure he did his best." River tells The Doctor trying to calm him down.
"He was supposed to protect her, and she died! She was your daughter too!..." The Doctor rambles.
"Everybody dies! I thought you would know that best, Sweetie!" River yells giving up hope of calming him down the way a normal wife would.
"I know." The Doctor says braking down, "I am sorry, Sherlock, I know you did your best, it's just everything that has happened to me I was hoping to keep my daughter." The group carries Amelia-Rose into the TARDIS and Sherlock immediately runs to the library, first place he had a conversation with her and steps in one step farther into his shell. The Doctor goes in search of Sherlock and find him sitting on the floor, eyes recovered, cheeks still wet. "Sherlock?" The Doctor approaches.
"Doctor." Sherlock answers without a hint of emotion in his
"Umm, do you want to stay here or do want go back?" The Doctor asks not sure of what he himself wants.
"I'll go." Sherlock says his façade breaking, "I miss her already," he cries, "will it get better?"
"Being honest, no." The Doctor tells Sherlock, "I have lost more than you could imagine, my friends, my family, even my home world, but I don't let that not allow me to enjoy the time I have with those people. The way I see it life is full of good and bad, the bad doesn't make it so you can enjoy the good, but visa-versa the good doesn't make it so that the bad doesn't hurt." Sherlock nods. "Do you still want to leave?" asks The Doctor, Sherlock nods again, "Ok," The Doctor says handing Sherlock a slip of paper, "this is my phone number, it will connect you to me, if you need anything just call. Now lets get you home." The Doctor land the day after Sherlock started traveling with him and Sherlock continues life, trying to wipe the bad a way.
