Pfffft, well this project took me a long time. Still not really statisfied about it, but i think that it worked out pretty well. Already came up with this in my holiday, so i had to wait a long time before i could work on it.
Please read the description below, it's a bit long but it will clarify certain parts in the video:
Moriarty hates Sherlock for something he's done and he swears he will get his revenge. One year later, Sherlock has long forgotten about the event and he meets a very special girl named Rose. As soon as he sees her he falls in love and he gives her his address in his own Sherlock like way. Rose goes to his apartment and rings the bell. Sherlock ,who was hoping she'd come, shouts: "Yes!" And he runs down to open the door as fast as he can. He sees Rose standing there smiling at him. They get into a relationship and are very happy together. This was the moment Moriarty was waiting for. He let some people capture Rose and Sherlock. He tells Sherlock through a video that he has to play a game with him. If he doesn't play Rose will die. The rules of the game are if one of them dies, the other one will be set free. Rose wakes up in a room where the sunfilters, which keep her from burning, are descending. She runs to the door and screams if someone can let her out. Sherlock who's in the same building hears her and runs as fast as he can towards the place where he thinks Rose's voice is coming from. He frees her with a card he found Moriarty put in his pocket. In the next game he has to take in some pills that will kill him and Rose is just in time to shoot the person who's forcing him to take the pills. After that the final game is about to come. Rose is running away from a Dalek and the doors close just before she can enter the other room. Sherlock calls her and asks if she's alright. To which Rose replies that she was not fast enough to outrun the Dalek. She tells him it's not his fault and that she wouldn't have missed it for the world and then the Dalek exterminates her. Sherlock who's struck by sadness jumps of the roof he was standing on and in that way commits suicide. Rose didn't really die though, it was a trick set up by Moriarty and as Rose survives, she has won the game and she is allowed to go home.She arrives home and has a very difficult time, because she is not able to cope with the loss of the love of her life. Then she meets the Doctor who asks her if she wants to go with him. Rose decides to leave everything behind and hopes that in this way she will forgot about her pain. So the story of adventures with the doctor starts. Rose tries to forget about Sherlock by letting the Doctor take his place, but he can never be the same man and the ache of not having Sherlock around continues to throb in the back of her head. Then she learns about the heart of the TARDIS. When the Doctor pops out of the TARDIS for a minute. She opens the heart and adsorbs the time vortex. With the time energy she brings Sherlock back to life, but it results in her own dead. The Doctor finds her too late...She's gone.
