Just after Guinevere and Lancelot episode.

As she watched Arthur leave holding onto to Morgana, her heart broke. His eyes swam with a thousand emotions and none of them she could read clearly.

Lying in the dungeons in the castle, she didn't believe that anyone would come for her, Arthur had made it clear that they could never be, but when Lancelot arrived it was a beacon of hope, a good man, a brave man cared about her and would die to save her but then he left. For all Lancelot's talk, he left with the words 'Something's cannot be' .

"I thought I would never see you again" Morgana said breaking her out of her thoughts.

"Nor did I, but thanks to you, Arthur came to save me" she said quietly, feeling like she couldn't breath as she spoke the words.

Morgana looked at Gwen "It was nothing to do with me, he was already packed when I got there" she said smiling and as if an afterthought "He was just as concerned as me" she said.

Gwen processed everything through her mind as she walked back to Morgana's chambers of course he didn't do it because Morgana begged him, she had been a fool. Arthur was a proud man and seeing her with Lancelot would have hurt him. Why had she been so silly she thought to herself.

She needed to go and speak to Arthur, no matter what their future holds the thought of Arthur thinking Ill of her she could not bare. She made her excuses to leave Morgana, saying she would visit Gauis to check her ankle. She was still in Morgana's dress, not wanting to leave this conversation until tomorrow, if the night passed she knew she would not be able to talk to him.

She took a deep breath and gently tapped on Arthur's door.

Merlin answered "Gwen" he said surprised.

"Merlin, is Arthur there" she said quietly.

"He's um not here at the moment he's talking to Uther" he said opening the door to let her in.

As he said this her stomach sunk, she had forgotten how Arthur would have disobeyed Uther to save her, she felt even worse.

"You can wait, he probably wont be long" he said honestly.

"Maybe I should go" she said losing her nerve, what could she say to him to make this right.

Merlin approached her and touched her arm "Are you alright?" he said looking concerned.

She half laughed "Not really" she said quietly.

"Lancelot" he whispered.

"Arthur.....well both, it's been a long day" she said.

At this Arthur entered his chambers looking very tired and annoyed, when he noticed Guinevere his heart sank, he really needed to be away from her right now, it made it so much harder for him to cope when she was near.

"Guinevere" he said and closed the door.

"I will go and fetch your dinner" he said giving Gwen an encouraging look and as he walked past Arthur a don't be a prat look.

Arthur walked past her and pretended to be interested in what was on his desk. "Is there anything I can help you with?" he said not looking at her.

She laced her fingers together and took a deep breath, he was mad.

"I am sorry to disturb you My lord, I just wanted to say Thank you" she said quietly.

"Of course, well it's been a long day" he said now turning to face her still looking upset.

She didn't move or look at him just in case she lost her nerve.

"You came not at Morgana's request" she said softly.

He sighed "No, it was my own" he said, she was not going to leave without talking.

She raised her eyes to look at him, but he was looking down with his arms crossed.

"I thought that I would not be worth saving" she said quietly getting closer.

"You are" he said.

"I am sorry for any harm caused" she said honestly.

He still could not look at her, he just shook his head, he could not tell her that seeing the way she looked at Lancelot tore his heart out. That the thought of them together made him feel sick.

"When you said that your father would not understand..... I thought that you had regretted what had happened with me" she said quietly looking down.

"No" he said in a voice that didn't sound like his own.

She didn't know what else to say to him she just said "Thank you" and went to leave.

"Do you love him?" he said quietly. He didn't know if he could cope with hearing her say yes, but he needed to hear it.

"I care about him, but I am certain that my heart belongs to another" she said but did not turn to face him , she started to make her way out of the door when he spoke for the final time.

"Thank you Guinevere" was all he could manage to say, he couldn't process the whole day yet, the hurt, the anger, the fear and the hope all of it swished around his head and heart.

When she left he slumped on his bed and a smile started to appear on his face 'my heart belongs to another' he said quietly to himself.

When Gwen left Arthurs room Merlin was waiting outside.

"So I will ask you again Lancelot or Arthur?" he said smiling, remembering back to the first time he had asked her that question.

She sadly smiled "I think you know the answer to that..... Goodnight Merlin and thank you for rescuing me"

"You're welcome, Good night Guinevere" he said and smiled .

It's a little sad, so please let me know what you think, I am thinking of doing a follow up with Lancelot returning!
