(AN: for all those who wish to know and care, this is set just before season 2 episode 12 the fires of Idirsholas.)
Gaius positioned her on the bed so she was lying on her back then swiftly left the room. He moved quickly outside to where Arthur and Merlin were training. "Sire." Gaius said with a bow. "what is it Gaius?" Arthur asked. "I need Merlin. It's a family emergency." Gaius explained carefully. Merlin looked confused. "Is it mother?" he asked. "it's a younger family member closer to your age." Gaius hinted. Merlin's eyes widened. "You don't mean.." he started Gaius nodded quickly before anything else could be said. Suddenly Merlin took off.
~Dream~
Mia was in an all-black room. "Young witch" a deep voice called. She looked around to find the owner and turned face to face with a dragon. She knew she should be afraid but was not instead she felt like she was in the presence of an old friend. "Who are you?" she asked. "you are destined for great things Mia. Things beyond your imagination." the dragon said. "Can you elaborate or are you just going to leave me hanging?" She asked. "Your manors are far better than that of your brother's. But there are thing I am not able to tell you." the dragon said. She sat down on the black floor in front of the dragon. "What is your name? You know mine but I don't know yours." She said. The dragon smiled. "I am Kilgharrah the last of my kind." Mia sat up straighter recognizing the name. "My father mentioned a Kilgharrah." She said. They sat in the silence. "What is so great about my desteny? I am no one." She said. The dragon let out a laugh. "You are more than you think. A young warlock by the name Emrys will need your help. He thinks his magic alone will save him, but he is wrong."the dragon explained. "you must leave now. Wake up." he breathed.
~End dream.~
Merlin sat at the dinner table silently every once in a while looking at Mia on the medical bed. Mia's eyes snapped open. Merlin looked over and saw she was awake Merlin's face turned to a grim expression. Mia slowly sat up wincing as the stitches pulled. She looked around and locked eyes with merlin. She pushed herself back, keeping the blanket tight around her, trying to gain distance between her and Merlin, almost falling off the bed. "What are you doing here?" she asked scared. "I could ask you that being you've been gone for seven years." He said in an angry voice his eyed changing slightly to gold. "You wouldn't dare use magic against me brother." she said. "What makes you say that Mia?" he growled. "Well for one My defenses are already up second you'd want know why I left." she said simply her eyes too starting to turn gold. Suddenly the door opened. Both heads snapped in that direction all traces of gold in their eyes disappearing. Arthur appeared in the door way. He looked at the face of his friend then to the girl. "Am I interrupting something?" he asked slowly unsure if he should leave quickly or stay to find the answer. "Not at all Sire." Merlin said quickly. Arthur nodded slowly still not feeling entirely safe between the two. "Gaius gave had me give you the day off due to a family emergency." Arthur started. "I wouldn't call it that." Mia mumbled. Arthur looked at her then continued. "So can I ask what you are doing here with the former captain of Camden's royal army?" Arthur asked glancing between the two of them. "Who? You mean Mia?" Merlin asked. Mia rolled her eyes. "No my invisible friend who's siting next to me. Yes you idiot!" Mia said. "I'm going to guess you've known each other a while seeing Mia already knows you're an idiot." Arthur said trying to ease the tension filling the room. "I've known this brat since she was in the womb." Merlin said bitterly. Mia crossed her arms. "I'm as much a brat as you are skilled with a bow." she declared with a raised eyebrow. "You're a dullard.' he said. "Oh I'm a dullard well I guess that make you a morosoph clod-pole." Arthur's eyes widened. "Merlin I think she has better vocabulary than you do." Arthur said in a loud whisper. Mia smiled. "Any other comeback, brother, or are you out?" Mia asked. "Brother?" Arthur asked shocked. "Yes twin brother actually." Mia said solemnly(?). Suddenly Merlin's anger let out. "YOU LEFT US!" He shouted at the top of his lungs. Mia bowed her head. "If you knew.."
"I DON"T CARE FOR YOUR EXCUSES! YOU KNEW MOTHER AND I NEEDED YOU!" Merlin shouted tears of anger threatened to spill over. "There were answers that I needed." Mia whispered. "YOU COULD HAVE LET US COME TOO. WE WERE A FAMILY AND FAMILIES HAVE TO STICK TOGETHER TO SURVIVE." he continued. She looked up at him in frustration letting him see the tears that had spilled over her cheeks. "I am glad I did not take you with me. If I did you would end up just like me. I would not wish that upon even my worst enemy." She whispered. She stood keeping the blanket to cover as much as possible then wobbled over to her bag. He knelt down and took everything out. All were pieces of armor then she set down a dagger in a sheath on the dining table. The handle was made of bronze and was shaped like a dragon. She smiled softly then started to put the armor on trying to keep covered. She finished but taking her sword and scabbard and attached it to her side. " Where do you think you're going?" Merlin asked. "Tavern." she stated. "Prince Arthur I'm ready to fight when ever you are. But let's just make it the knights and any others you want to be there." She said and walked out. Merlin slumped into the chair elbows on his knees and his hands held his head down. "Are you going to tell me what's going on or am I going to have to guess?" Arthur asked squatting in front of Merlin so he could try to look at him in the face. "Mia and I are twins we were very close as children we did everything together. Then one night when we were 13, she took mother out side and they talked for a long time, then they came back in. in the morning Mia was gone. Mia had a great job and was earning over half our total pay. We tried to look for her but couldn't find her. I promised myself I would never mention her again." Merlin muttered. Arthur nodded. "You can have the rest of the night off." Arthur said filling the silence. "Do you want to be left alone?" Arthur asked. He saw Merlin nod and left quietly. He turned and headed to town, to the tavern.
