How exactly did he get inside Morgana's chambers?

He stared blankly at the massive room before him, trying to remember what exactly happened in the past couple of hours. He was at the tavern drinking ten beers and now he was standing at the entrance of the lady's chambers.

He dragged himself across the room searching for anything to lie on. Because of his blurred vision and the darkness that covered the room, it was hard to clearly see where he was and where he was going.

As he tried to focus through his dizziness, he tripped and face planted onto the wooden floor. He sluggishly got up and reached for his feet to make sure he didn't break any of his toes.

Instead of his feet, he grabbed on to a piece of clothing. He gripped onto it and started to observe it with his hands. He suddenly realized that it was one of Lady Morgana's night gowns.

He slipped the gown over his body and tied the string behind him. It fit perfectly and was surprisingly comfortable. He slid his hands down his body as he imagined what he would look like in a slender silk dress. He probably would have beat Morgana's beauty wearing any of her dresses.

After a couple minutes of posing and flirting, he laid down and slept instantly.

"Arthur? Did you hide my neckerchief somewhere?"

"Well it's not my responsibility for your scrappy fabric, Merlin."

"But I left it here when I was cleaning the horses- umm, never mind."

Merlin snickered as Gwaine continued to snore in a pile of hay with only a red cloth to cover his naked body.
