While Spencer and Morgan were walking over to see Gideon, Hotch intercepted their path.

Hotch greeted them, and then addressed Morgan. "I know I told you to see Gideon, but I want to ask Reid a couple questions first." He turned his attention to Reid. "Do you know who I am?"

Reid thought about it for a moment. Honestly, he had no clue, but the man in front of him seemed to command an air of respect. This must be that Boss everyone talks about. He thought. Wait, didn't the wizard sound like she was talking very formally to some man on her head-thing? He must be the little person she was talking to! But he's so much bigger in person… Spencer looked up at Hotch. "You must be the little person who was talking to the wizard, but you don't seem very little now. You're her boss, aren't you?"

Morgan gave Hotch a what-did-I-tell-you look, but Hotch continued without batting an eye. "Yes, Reid. I'm Aaron Hotchner. I'm Garcia's boss and yours."

Reid got very excited and only heard half of Hotch's words. My boss is a leprechaun?

Since Reid wasn't speaking, Morgan thought that he would sum up Hotch's words for him: "Reid, this is your boss. We call him Hotch, but Garcia also calls him sir. Okay? My name isn't 'Sir', his is." Spencer just continued staring at Hotch. Morgan took this silence as a way to leave.

"Well, Hotch, we better get Reid to Gideon. See if he can't make any progress." Morgan took Reid by the shoulders and steered him to where Gideon was standing nearby. "He's all yours," Morgan said as he let go of Reid.

…

Gideon and Spencer arrived back at the office in no time flat. During the car ride, Spencer kept staring at Gideon and trying to collect scattered memories of them together. He knew that the man's name was Gideon, but he couldn't remember much else. They walked in the doors and Gideon led Reid over to a little table and chairs.

"Spencer, we are going to play a game of chess. You remember how, right?"

Spencer did remember how, and that he often played chess with Gideon…and often lost. Remembering how many times Gideon had beat him, Spencer resolved to win this time. As they set up the pieces, Gideon kept asking Reid as series of nonstop questions.

"Do you know who I am?"

"Of course," Spencer said confidently. "You're Jason Gideon." Then Reid remembered how Gideon had always been there for him; to give him advice and help him whenever he was in trouble. "And you're my father."

Gideon's eyebrows shot up and he smiled. "Father? Well, I don't know about that, but you've always been like an honorary son to me. Now, do you know where we are?"

Spencer looked around and moved his pawn forward two spaces. "I think we're in the same office that the wizard works in."

Gideon wasn't satisfied. "Come on, you know where we are." He moved his pawn and took Spencer's.

Spencer looked around once more. I don't know where we are, he thought. But as soon as that thought came to mind, the name of the place did too. "Quantico, Virginia," he said, surprising himself. "The office of the BAU."

Gideon smiled again. "Very good." He and Spencer took a couple more turns each. "Now name the members of our team."

"Let's see," Spencer thought for a moment. "There's the leprechaun, JJ, the wizard, Sir, me, and you, Dad."

The looked on Gideon's face was very strained, like he was trying to keep a straight face while annoyed that Spencer didn't know everyone's real names. "You're missing someone."

He had to think for a little while longer before he realized who he was missing. "Oh, I think her name is Emily, and I don't think we talk much, but she's funny. I haven't seen her at all today."

Gideon nodded. "That's good you remembered her name. Can you tell me everyone else's real names?"

This is hard. Spencer thought about Gideon's question for ten minutes before he finally answered: "Your name is Gideon and you're my father, the leprechaun's name is Hotch, the wizard is Garcia, JJ, Emily, and…sorry, I can't remember Sir's name."

"Morgan. Sir's name is Morgan." He moved a rook to his left which Spencer took using a horse.

Strauss chose that moment to walk in. "Jason! What are you doing? Isn't there a case you should be solving, and why is Spencer just sitting here with you?"

Gideon answered without looking at her. "Spencer has a bad case of amnesia which he got from an accident at the crime scene. I'm helping him to get his memory back." He moved his Queen.

"And why wasn't I informed of this?"

"We were a little busy, Erin. Between helping Spencer and trying to catch the UnSub, there has been little time for unnecessary phone calls."

Strauss was angry. "Unnecessary? I assure you, that it is perfectly necessary to inform your superiors of any-."

Reid stood up and shook her hand. "Thank you Miss Dictator. Don't worry, your kingdom is under control and the invading troops should be driven out in a couple of days."

Gideon tried not to laugh at the shocked look on Strauss' face. "Sorry, he's not in his right mind, but his is partially correct. We should have the UnSub in police custody very soon."

"I will be expecting that, Jason." She started to walk away, but turned back for a moment. "And please, do get him back in the correct frame of mind."

Gideon turned back to Reid and their chess game. "It's your move."
