The first time it happens I'm inserting an IV. It isn't noticeable to an outsider, only to me. I don't receive weird looks; no-one grabs the IV away to do it for me. A tiny jerk. Nothing.

I sit at home watching the rain out the window, deep in thought. How fast will I fall apart? How long will I still be capable of enjoying my life? What will Allison think?

Cameron comes in the front door, hair dripping even after the short run from her car. I turn to her and try to smile. She comes over and wraps wet arms around me, rain scented hair cascading over me as her head rests on my chin. "Hey, Rem."

"Hi." I whisper. She backs away a little and sits beside me, taking my hand. There is a frown wrinkling her forehead.

"What's wrong?"

I look at her. Her eyes search mine. I look away. "My hand twitched today."

"As in…" she trails off. I nod. Chorea.

Her free hand reaches out to stroke my hair. "Oh, Rem." I can hear the devastation in her voice.

I chuckle hollowly. "We knew it was going to happen sooner or later."

She sighs. "I know."

I move towards her then, allowing myself to feel the pain I am experiencing. That she's experiencing. Cameron rocks me gently, her lips in my hair.

At least I'm not alone.
