Eurus waits in her cell. Her calculations aren't working but he said he'd come back. He promised.

Every time she closes her eyes now there is no plane but instead her cell and a man playing a violin.

The plane has landed, replaced with longing, so she trusts in her older brother.

He walks in- she hears the door hiss.

Footsteps and the soft noise of fabric hitting the concrete floor.

He plucks a few strings.

He begins to play.

I missed you. We miss you. We want you to come home Eurus- come home to us. We want to bring you home.

She breathes in, feeling their love and their hope and their despair and their loss and one million other feelings which are encompassed completely by the word care.

She picks up the violin from her bed. Her brother stops, watching as she tucks the instrument beneath her chin. His face lights up just as it did when she first played for him.

Eurus begins to play.

I'm afraid- so very afraid as the plane flies over the body of water. It's falling faster and faster yet there is no impact- surely there should be impact? There is no one else. It's me.

The tune is of fear and wistfulness. It is flying and never coming down and falling forever, deeper and deeper and deeper and deeper and deeper, yet never reaching the city. The melody tells of being alone.

She stops.

Her brother picks up the tune.

I'm sorry. I'm so sorry. We miss you. We love you. You don't have to fly if you don't want to- just reach out for my hands and I'll pull you down. I've missed you.

He stops again, she closes her eyes.

I miss you too. She plays.

More than you know. He plays.

I want to get you out of here. Says Sherlock. I want to help you.

I want to get out of here. Says Eurus. I need you.

Mycroft thinks you are a threat.

I am. I can change. You made me change last time- you saw. That experiment-

You saved John Watson.

I saved myself from your hatred. I see now the path I must take. I miss mother and father and you.

And Mycroft?

He gave me treats.

We all miss you. We are all afraid.

Of me? For me?

Both. Victor.

Victor. She feels the deep sorrow as her brother plays.

It's pain. That is pain.

She stops and he stops too.
