Warnings: Gaius telling those whippersnappers what's-what.
This one is entitled:
4.07: Because the Way Gaius is Unappreciated and Disrespected Angers Me
"No one is to take offense at this."
"Really?" Gaius said, his eyebrows drawing together. "Because, frankly, Agravaine and you, Arthur—I'm offended."
Arthur blinked at Gaius with some confusion, and the old man stood up.
"I have been working here since before you were born," Gaius told Arthur. "I served your father faithfully, Arthur, the same way I serve you. Even so, I have been mistreated—first the Witchfinder and now this?"
Arthur winced. Agravaine started to say something, but Gaius cut him off.
"Sire," he said. "I am an old man. I haven't much room for demanding things, I know, but even so, I think I deserve some respect for who I am and what I do. And what I have done. I helped you take back Camelot, Arthur."
"Of course, Gaius," Agravaine said, "and we understand…"
"And so," Gaius said, glaring at Agravaine. "And so, I think that I deserve more respect than to be nearly dragged here, flanked by guards, and to have it insinuated that I am a traitor. If you wish to speak to me, I will be in my chambers. And if you wish to question me, I will tell you ahead of time that as an old man, I have many secrets. And some of them, I will keep."
And then he turned and he walked out. Agravaine turned to Arthur, enraged, waiting for the order to go and make Gaius return. But Arthur shook his head, and he let Gaius go.
