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

Last time on ER. Flashes to Susan standing in the doorway Flashes to her sitting on the couch Flashes to Mark and Susan making out Flashes to Doug, "Welcome back, Susan" Susan: "Thanks" Flashes to Mark, "Where we were"

The next day Susan walks into the ER. Mark is already there. She walks up to him, slips her arm around his waist and kisses him, first on the cheek, then on the lips. "Hi sweetie." Haleh, who is standing there, looks up, "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."

Susan is greeted throughout the day with surprised faces. The word is spread that Susan and Mark are FINALLY an official item. "I was wondering how long it was going to take you two to finally realize you were sole mates," says Carter to Mark, "everyone else already knew it, we were just waiting on you guys. I'm glad you guys finally realized it too."

It's a slow day that day in the ER. Susan and Mark are both in the lounge working on some paperwork, chatting a little while they work. Carol runs in, "I need both of you in the ambulance bay, multi trauma coming in, 4 car pile up. Several kids involved."

Mark and Susan drop what they are doing and run out into the ambulance bay. She finds the whole ER gang in the ambulance bay. 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."

"Okay now everyone back to work," says Weaver. The crew scowls. Doug pours some champagne on her head. Everyone laughs.

"Doug." says Weaver.

"What?! Oh come on.that was funny."

"Just get back to work."

"Oh alright." Doug walks behind Weaver, sticking out his tongue. Weaver who apparently saw him says, "Grow up Doug."

"NEVER!"

The day ends. Mark and Susan leave the ER hand in hand. Doug and Carol are watching them leave.

"They are so cute together. I'm so glad she came back. They belong together," says Carol.

"I know," says Doug. "Just like us. Hey catch up with them real quick, we're off in 2 hours. Maybe we can double with them, meet them somewhere."

"Okay." Carol runs and catches up with Mark and Susan. "Hey guys, Doug was wondering if you guys wanna double with us later. We're off at 8. We could all do something?"

Mark and Susan exchange glances. Susan nods. "Yeah okay sure! Meet us at Harry's Lounge (just making up something) when your off."

"Okay," says Carol, "we'll see you later then!" She walks back to Doug, "Harry's lounge, after work."

"It's a date," Doug kisses Carol. "I better get back to work before Weaver fires me," chuckles.

It picks up a little. One GSW and a car accident. Both pretty minor. It's finally 8:00 and Doug and Carol are just walking out when Kerry walks up. "Doug, can you do a consult?"

"Sorry Kerry," Me and my honey are off. We gotta go meet Mark and Susan. I'll have to catch you later."

Kerry scowls and limps off. Doug and Carol arrive at Harry's bar. Mark and Susan are making out. "Ahem," Doug clears his throat. Mark and Susan ignore him and continue kissing. "We can do that too." Carol and Doug start making out. Mark and Susan stop and are watching Doug and Carol. "Ahem." Mark clears his throat. Doug and Carol stop.

"Now that my friend" remarks Doug, "is called courtesy." He chuckles. "I'm just giving you a hard time. I'm really glad to see you guys together like this. Gives us fresh gossip." Chuckles.

The four enjoy a night out, some drinks, some laughs and some smooching.

A few days pass, then a few weeks, then a couple of months. It's now been exactly 4 months since Susan came back and her and Mark became an item officially. Susan is standing at the front desk. Head resting on hands looking tired. Mark walks up, quick kiss. "Rough day?"

"No, I'm kinda tired."

"Well, don't wimp out on me. It's our four-month anniversary. I have something very special planned."

"I know. And I can't wait. Two hours and 47 minutes to go!" Susan smiles.

Chuni walks up. "Sorry to interrupt guys but Mark your needed in Curtain Two."

"Alright, later baby," he says to Susan.

That evening after work 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...
