Dark Emma, Swanqueen friendship
The right choice
Chapter 1
"I can't leave her, she's pregnant!" Robin desperately repeated. "Besides, I just can't let Roland loose his mother again! These past months have been hard on me, but somehow we managed to work it out and…" He shrugged his shoulders, struggling for an explanation. Regina just stared unbelievingly before she stated without any emotion:
"She is a wicked witch who murdered several people, including your wife, threatened all of as with dead more than once, deceived you to leave town with her so she could seduce you… and yet you do not even consider coming back with me?"
Her former love just frowned and raised his hands helplessly. Without another word, Regina turned around on her heels and made an exit.
"Regina wait!" he called after her. "I-"– "Don't you ever again address one single word at me." She snarled without facing him. Despite her words Robin made an attempt towards her, only to be stopped by Emma who put herself in his way. "I think she made herself very clear." She stated indifferently. "But-" when the man struggled for words again, trying to get past her, Emma clenched her fist, ready to use bare force to hold him back. But Regina's apparently calm voice ended the incident before it could escalate. "Miss Swan. Would you be so kind to accompany me to the car so we can leave this inhospitable place as soon as possible?" With a last look at the miserably man and the smirking woman behind him, Emma nodded and turned her back at the scene.
"What was that about, Miss Swan?" Regina asked, after they left the building. "Your interference was absolutely unnecessary." Emma shrugged her shoulders. "I know. I just wanted you to know, that I got your back in situations like this." The other woman laughed bitterly. "I have been the evil queen – I have handled worse before, so I think I can cope with something like this." After a short pause she softly tapped Emma's arm and added in a more gentle way: "But nevertheless – thank you Emma. I appreciate the attempt." The saviour turned her head in surprise. Had she heard correctly? Had Regina, former evil queen, just been showing her gratitude? Observing her look the brunette snorted indignantly. "Would you stop looking at me like a deaf puppy, Miss Swan! You heard me, I won't repeat myself. And now – drive me home," she ordered, waving her hands while entering the bug. Emma just smiled. Some things just won't change. At least, not in such a short time.
Sitting in the car, where Lily had been waiting, the three women quickly got lost in their own thoughts, Regina no doubt repeating over her last moments with Robin again, trying to understand what had happened, Lily perhaps looking forward to meeting her mother, not sure, what to expect from this reunion. Emma had a bad headache. Since she chased Lily in her bug, nearly shot her for threatening her parents and then kind of reconciled with her, she had something like a dark cloud hanging in her had. Thinking of her parents she soon had to face again and their betrayal didn't do any good, so she tried to concentrate on other things.
"You know," she said, first thing that came to her mind; "Operation mongoose is not over yet." She earned a disapproving look from Regina. "Excuse me Miss Swan?" Emma tried to smile. "Just because Robin may not be your happy end, doesn't mean you won't get one. We will get the author and find you a new one." The brunette sighted. "I can not recall asking you for an opinion or your condolence. But just to make sure next time; I do not require your kind words or charity." Emma rolled her eyes. "Gee, I thought we were past that, Regina. We are friends so let me show a little concern for you once in a while."
