Summary: My outtake on what should have happened if Susan would never have left.

Last time on ER. "SUSAN?!?!" I thought you left." "I did. But I couldn't do it because Mark and I are in love." She smiles.

"Well it's about time honey," says Haleh hugging Susan, "Congratulations. You too Mark."

Doug shakes a bottle of champagne, aims it at Mark and Susan and pops it open. Champagne sprays all over them! "This is a celebration, of two soul mates who finally realized they aren't just best friends. May your romance never end." Doug pours a little bit of what's left of the champagne into some glasses and hands them out. He raises one glass. "Here's to two of my best friends for finally finding romance."

"I'll drink to that," says Mark. Everyone raises their glasses. Mark and Susan who are holding hands, kiss." Mark and Susan are at Antonio's, a very nice Italian restaurant. They are sitting across from each other. Both of them have their hands on the table, intertwined with one another's, gazing into each other's eyes. "I love you Susan."

"I love you too Mark."

Mark lets go of Susan's hands and reaches in his coat pocket. He takes out a small box and opens it. Susan gasps.......

Inside of the box is a huge sparkling diamond ring. Mark looks at Susan. "Susan, I love you. I loved you for a very long time. You've seen me through so many hard times and we've had a lot of good times. You've rescued me from bad blind dates, helped me through my divorce with Jen and been the best friend that I could ever have. I don't know what I'd do without you. And.I don't know what I would do the rest of my life if you weren't in it. Susan, I have no doubts. You're my soul mate. I want to spend the rest of my life with you. I want you to be my wife. Will you marry me?"

Susan puts her hand over her mouth. Tears are coming from her eyes. "Yes! Definitely Yes! Mark, I love you so much and I couldn't imagine anything else better than being your wife. I can't wait to spend the rest of my life with you, my soul mate." Susan leans in and her and Mark kiss. Mark slips the ring over Susan's finger. Susan grins and puts her hand out in front of her palm down. "It's so beautiful Mark."

"Not as beautiful as you are."

Susan blushes and looks down at her hand again. "I love you!"

"I love you too!"

The next morning the alarm goes off at Susan and Mark's apartment they'd been sharing. Since Susan hadn't left and Mark had taken over the apartment when they thought she'd be leaving they decided to just go ahead and share it. Susan rolled over and slapped the alarm clock off and groaned. "Ugh," she thought to herself, "time for work already?" She then remembered that her and Mark had gotten engaged last night. "Unless".she thought, "that wasn't a dream was it?" She looked down her hand and saw the ring shimmering. She smiled. "Thank God, it wasn't just a dream.

Just then Mark knocked on her door. "Come in," said Susan.

Mark enters the room with a robe wrapped around him and two trays in his hand. "Get back in bed," says Mark. "I brought us breakfast in bed." Susan smiles and climbs back in bed. Mark lies down next to her, hands her a tray and then keeps the other tray for himself. "So how's my fiancée doing this morning?" asks Mark.

"Mmm that sounds sooo good! I'm the future Mrs. Susan Greene. Man! I can't wait!" They kiss.

A few hours later Mark and Susan arrive at work together hand in hand. Doug and Carol are standing at the counter looking over some charts when they notice that Mark and Susan have just entered. "And how is County's best couple today," asks Doug?

"I thought we were County's best couple," whispered Carol.

"We are just humor them," chuckled Doug.

Mark holds up their hands and points to the ring. "We're engaged that's how we are." Everyone stops what they're doing and looks at Mark and Susan. Carol smiles. OH my gosh, you guys! Congratulations! That's so wonderful." Carol walks over and hugs Mark and Susan together. Doug walks over too, "Oh hell, let's make it a group hug, Congratulations you guys! We're happy for you."

Weaver walks in and notices their big group hug, "Everything alright she asks?"

"Mark and Susan got engaged Kerry," says Carol.

"Oh that's great news. Congratulations. Now get back to work. We've got patients to attend to," she says sort of dully.

Doug chuckles. "She seemed thrilled as usual. Well I do have a few patients to take care of, but Carol and I want you to know that, (mocks Kerry) it's great news, Congratulations. No, we really ARE happy for you guys and anything we can do to help with the wedding just..

"Actually," interrupts Susan, "there is something you can do for our wedding."

"Sure what is it," asks Doug?

"Will you two be our best man and maid of honor?"

Carol smiles, "We'd be honored."

"Yes we would," remarks Doug, "besides it'll give us practice walking down the aisle together," he winks.

Carol smiles and bites her lower lips and just kind of shrugs it off. "Whatever you say Doug."
