Merlin got up and hurried out of the room, with Arthur following. As they were walking, Merlin started talking. "You remember when Gwen was accused of planting a poultice in your room to make you fall in love with her? Well, it was actually Morgana who did it- she wanted Gwen out of the way so she could become Queen. I couldn't let Gwen die, so I decided to make another sorcerer take the blame."

"How did you get another person to do that?" asked Arthur.

"You'll see," Merlin replied cryptically.

They finally reached Gaius's chambers. Merlin opened the door and walked in, holding it open for Arthur. Gaius was there, making some sort of potion. "Good morning, Sire," said Gaius, bowing. "Merlin, what are you doing?"

"I'm showing something to Arthur," replied Merlin. "This is how I made another person take the blame for Gwen." He paused, then spoke. "Miht dagan, beþecce me. Adeadaþ þisne gast min freondum ond min feondum." As he said the last word, Merlin's eyes flashed gold, and there was an small explosion. When the smoke cleared, Dragoon the Great was standing where Merlin had been. "What do you think?" he said.

"I knew I recognized your eyes!" exclaimed Arthur.

Dragoon- Merlin- smiled. "Yes, yes, very good, Arthur-"

Arthur interrupted Merlin. "But- why did you have to be Dragoon? Couldn't you just have performed magic as yourself?"

"That would have been highly stupid," replied Merlin. "The point was to create a disguise where I could use magic openly, hence the aging spell. I had planned on being caught then turning back to my regular age, so that everyone would think that the sorcerer had escaped and I could get back to my duties."

"Why didn't you?" asked Arthur. "You were an old man up until the last minute."

"I tried reversing the spell, but I initially couldn't- I had to use a potion Gaius created. Speaking of which...Edniwe min geoguð!" There was another explosion, and Merlin was back to normal. "Anyway- I grew better at reversing the spell the more I used it."

"When else did you use it? Aside from the time you used it to kill my father."

"Firstly, I didn't mean to kill him. Agravaine put an amulet on him that would reverse any healing spell that was cast. Secondly...I used it to destroy the fomorrah that Morgana was using to control me, and I used it to plant an enchanted poppet in Morgana's room when she and Helios took over the castle. You remember she couldn't cast any spells? That was because of the poppet."

"Yes, I remember...you said you used it to destroy the fu-"

"Fomorrah," Merlin interrupted. "Morgana captured me, and put a fomorrah head in my neck to control me. The fomorrah would wipe my mind blank except for a single thought- Morgana tried to make me kill you. Luckily, Gaius was able to paralyze the fomorrah and restore my mind, and I destroyed the mother beast."

"And that's it?"

"That's it for all the times I've used the spell," said Merlin. "What do you want me to talk about next?"
