A Viola's Song

Merissa

The pool, both the Holmes thought to themselves at the same time.
All Sherlock could think of was Irene.
All Viola could think of was Hannah.
Viola arrived at the pool before Sherlock did. The visit to Irene's flat had made his trip longer.
When Viola arrived, she obviously couldn't help but feel scared. She just hoped the Watsons were safe.
Sherlock just hoped Moriarty didn't have Irene hostage, though his instinct told him otherwise.
Both the Holmes could feel their hearts pounding against their chests.
When Viola arrived, she felt a sudden burst of confidence and walked swiftly towards the entrance.
She entered dramatically through the door and heard it squeak as it shut behind her.
"I'm here, then, what do you want?" she called.
She heard distance footsteps and a door opened across the room.
The voice that spoke was high, but not Moriarty's voice, a woman's voice. No, not even a woman, a girl.
"Well, then, Viola. You made it to me. No one ever gets to me," the girl's voice said, still hiding somewhere, Viola recognising the similarity to what Moriarty had said to Sherlock when he was faced with this situation, "Most people, if even, are victims who, then, are only exposed to workers. These workers aren't even exposed to him.
The only one who ever got to him was Sherlock. But not me, no."
The girl stepped out from behind a cabinet.
"No, no, never me. Not Merissa Moriarty. Not Jim Moriarty's daughter."
"I didn't get to you," Viola said. "You invited me."
"That I did, didn't I? I've been watching you. Moriarty had been watching Sherlock for a long time and he had never been ready to be exposed to me, him being so obsessed with..," Merissa cleared her throat, "..mum. But you had the qualities because you have just a bit of her in you. You were and are ready for me."
During the time Merissa had been explaining this, Viola had kept a straight face and showed no reaction to Merissa calling Irene "mum."
"I know what you're thinking," Merissa started again. "I'm not going to hide it. Short version, Irene is my mum. Long version, well..."
There was a silence between them.
"So, in fact, we are, half-sisters?" Viola said, breaking the silence.
Merissa nodded and smiled slightly. She put a finger to her lips.
"Shhh, mustn't say it aloud. We don't want Sherlock to know the only woman who ever mattered to him also loved his archenemy."
Viola made sure to keep her cold, emotionless mask up, but inside, she was screaming "NO!" over and over and over...
"She's a dominatrix. It's not that she necessarily loved Moriarty, she probably just, you know, sex," Viola said calmly.
"I could say the same for Sherlock," Merissa taunted, but Viola could see that she was a little hurt at the fact that she most likely wasn't born out of love.
"Come on, that's probably not the first time you've heard that. I know it's not the first time I have."
Merissa opened her mouth to say something, but before she could, the door Viola had used to enter the room slammed open. Sherlock walked through, out of breath.
"Ah, Mr. Holmes, a little late, I see!" Merissa exclaimed.
