"How are you feeling?" Asked Gaius.

Merlin rubbed his head. "Sore," he admitted. "I've got a massive headache."

"I'm not surprised what with that huge bruise on the back of your head. Someone knocked you out, and they were pretty brutal about it, too," Gaius told him.

Merlin brought his other hand up to his head, but when he tried to feel the lump from where Drien had struck him, he yelped and curled his fingers as though they were on fire.

"My hand..." Merlin said meekly, looking at it. Arthur saw for the first time that it was bloody, and the fingers were crooked and bent.

Gaius sucked in his breath and examined them while Arthur watched worriedly and Gwaine seethed behind him.

"These are all badly broken, Merlin," Gaius said gravely. "They'll be out of action for quite a while."

He told Arthur to collect bandages and as the prince went to get them, he began cleaning Merlin's hand, saying,

"Where else does it hurt, my boy?"

"Head, my head really hurts..." Merlin put a hand to his side and hissed. "My ribs, and my back."

Gaius wasted no time in pulling off Merlin's shirt, careful of his hand, and laid bare his purple, blue and green shoulders, ribs and upper back.

Gwaine and Arthur sucked in a sharp, collective breath.

"Merlin, what happened?" Gaius breathed.

Merlin looked down at himself, seeming slightly surprised.

"I'm not sure... I'm trying to remember, but I know I've got a massive concussion and I can't quite think-"

Merlin's eyes suddenly seemed to come into focus, and they widened as he saw bolt upright, startling Gaius, Arthur and Gwaine.

"Drien!" He shouted. "I've just remembered! He's an imposter!"
