From now on, everything single thing which happened during seasons 1 and 2 happened, except for the very ending of season 2
"…I would rather die than be with you, Guy of Gisbourne. I love Robin Hood. I will marry Robin Hood. I love Robin Hood." Marian felt freedom in her statement. It was true; she knew to whom her heart belonged to. Why did she have to play these games with Guy, she didn't know, but it was truly better late than never to express how she felt.
"No," Guy whispered to himself, his face falling. Rage, sadness, betrayal most of all, filled up inside of him like a balloon being filled with too much water and could pop at any moment. Marian was smiling and laughing, pleased with what she did. It was time for him to know. No more of this charade between her and Guy.
Without thinking, with his sword pointed in the direction of Marian, he ran to her, about to stab her in his rage, but he stopped right in front of her, realizing what his action would mean. He grabbed her arm and shook her violently. Marian didn't even flinch when he forced her to look at him straight in the eyes. She saw the rage, the betrayal, and the heartbreak in his blue eyes, but she didn't care. He was an evil man; he didn't deserve any affection from her, despite his claims that she would make him a better man.
He clenched his teeth and raised his sword up. Marian gasped. His sword pierced the ground right next to her. He released his grip on her, unable to speak. Even if he were to speak, what coherent words could he utter to her? This was the end of his redemption, his chance at a better life. Any possibility of a relationship between them was over the moment Marian declared her love for Robin. He had felt pain during his life, intense, deep pain, but they weren't like the pain he felt in his heart in the sandy and dusty courtyard. This was a pain of a different kind.
Noticing Robin and his crew members entering the courtyard, Guy ran off into the other direction, leaving Marian there. Perhaps she could realize how her words affected Guy. No. It was too late. She didn't love him; it was evident.
Vaisey was about to mount his horse and run off, as well, had it not been for Robin, who shot him in the back with three arrows. Guy gasped at this second turn of events. With a groan, Vaisey slumped to the ground.
"You will pay for this, Hood! Watch! The days following will make you regret it!" he croaked, before he died on the sand.
Guy was happy that this man, this poison, this torture in human skin, was gone. But that happiness was short-lived, because his anger at what Marian did to him overwhelmed any feelings of joy at that moment. He mounted his horse and rode away. Knowing that he was alone, he allowed himself the one thing which he forced himself not to do, and that was to cry.
From the distance, Marian noticed the sadness in his eyes. She would never regret what she did and said. She defended King Richard from Guy's sword. She told him the truth. Yes, she risked her life, seeing that Guy almost killed her in his rage, but that almost-killing showed that Guy had a tiny dot of decency. Still, that would never make her love him. Let him suffer or whatever.
She jumped when Robin touched her arm.
"Marian?" he said, looking at her with concern.
"It's nothing, Robin," Marian replied, breathing a sigh of relief. "I'm just glad that he is gone from my life. I can be with you now."
Robin kissed her on the forehead and held her hand. "Let's save King Richard and then return to England and marry."
