The following morning Susan walked into the ER to start her shift. "Doctor Lewis, this was left for you during the night." Jerry handed her an envelope.

"Thanks Jerry, do you know who left it?" Jerry shook his head before going back to what he had been doing. Susan looked down to the letter that lay in her hand. The print was very neat, and somewhat familiar. She walked into the lounge discarding her jacket before sitting at the table to open the letter. It read:-

Dear Susan,

I am sorry I am not doing this in person but I can't. I'm leaving Chicago. I can't handle it anymore. If you think I was bad when he was missing, this is worse. It's killing me seeing him everyday. The reminders I get everytime I see his face are unbearable. I'll never move on from losing Christopher if I keep seeing him.

I spoke to Eleanor last night and she was pretty upset about Christopher and with Carter for everything he has put me through. She is behind me 100 and I hope you will be too.

I don't know where I am going or what I am going to do but when I do eventually find somewhere, you'll be the first to know. Susan you are my best friend. You've been there for me all those times when he wasn't. You've picked me up from my down days and joined in my happy days. I can't thank you enough for everything that you have done for em. There are no words that describe exactly what you mean to me. Just know that wherever I am I'll be thinking of you. I really couldn't have coped these last few months without you.

Give Victoria a big hug and kiss from me. tell her auntie Abby loves her lots.

love you too, your best friend

Susan stared at the letter. "She's gone."

"Who's gone?" Susan hadn't realised anyone was in the room or that she had spoken out loud until she heard Carter's voice.

She looked up to him. "Abby's gone and it's all your fault."
