Potter made himself disappear from the room he was in, only to reappear at his desk at the Ministry of Magic. There, he met with his co-worker from before.
"Apparition." Eliot laughed, "We don't see you do that every day."
"I don't have time for jokes." Potter told him, "I need your help."
"Help?" Eliot questioned, "I'm sorry, Harry, but I've already got enough things to do..."
"Forget about them!" Potter interrupted, "Remember that formula I mentioned earlier? I was right, a muggle did steal it. And unless we hurry, he may do some serious damage with it."
"I'm not saying I wish I couldn't help." Eliot said, "But I got too many things to do which also take priority. So even if I help you prevent... whatever this damage is you're talking about, it could mean jeopardizing something else. I'm sorry, but I can't help you."
In his rage, Potter would have kicked his own desk. But that's when something else came to mind: "That man you captured."
"He still hasn't changed his story." Eliot said, "Why?"
"Take me to him." Potter asked him.
Eliot looked at him in disbelief: "Why would you want to see him?"
"No time to explain, just take me to him." Potter replied.
Eliot couldn't quite understand. But he shrugged it off and lead Potter to where he requested.
Down in the Ministry's dark dungeons, which still give Potter the creeps despite the fact that he's been down there on several occasions, he and Eliot were walking to this one cell. From what Potter had heard about this man, they had no real reason to send him to Azkaban, the maximum security prison, but they had no reason to let him loose either. So the Ministry's dungeons were the only other option left. This one cell had the appearance of a large cube, wherein there was a bed, a muggle-toilet, it had all the seeming of a regular prison, if it wasn't for the fact that the cube was made out of pure energy. On the bed, there was a man, dressed in a black suit, using what looked like a green trench coat as a blanket. Potter coughed so to draw this man's attention. The man stood up. He wore a mask that covered his face, and had the same color as his coat.
"A new guy." the man sneered, "There are only so many times that I can tell the same story to so many people. Why don't you just keep a recording if you keep forgetting it so easily?"
Potter knew this was meant as an insult, but he didn't let that get to him: "Are you the one who calls himself the Green Lantern?"
"Who's asking?" the man, or the Green Lantern, asked.
"My name's not important right now." Potter replied, "What is important is that you hear me out."
"Hear you out?" the Green Lantern didn't understand, "That's new."
Potter didn't know all the details of what's been going on when this man had been interrogated, so he doesn't always understand the man's reactions. But he continued anyway: "I understand that you keep telling the same story. How you found the magical ring first, and found the technical ring later."
Though there was a hesitation, the Green Lantern replied: "Yes."
"And you expect us to just take your word for it?" Potter asked him, "We allowed the first Green Lantern to keep the ring for himself, because he had proven that he wanted to fight crime with it, and nothing else. A few years ago, we see you using it, only to find out later that it's first owner is dead."
"I told you people already." the Green Lantern sounded furious, "I found him dead, and I took his ring, because it wanted me to take it."
"But then, coincidentally, you also found the other Green Lantern's ring."
There was that hesitation again, but the Green Lantern persisted: "How many times do you people want to hear me say it?"
"Look, for all we know your story is only partly true, or not at all." Potter explained, "Don't you think it's a bit of a coincidence that you just so happen to find both rings?"
"And for that you capture me." the Green Lantern lauged, "Because of my rings, you can't get close enough to take them away from me, so instead you create this barrier from which I can't escape unless I give you the magical one."
"It's like this..." Potter explained, "... from what my co-workers tell me, they have no real reason to trust you, so they can't know for sure that you should have that ring. Which is why I want to make a deal."
Both the Green Lantern and Eliot looked surprised at that, but it was Eliot who spoke first: "A deal?"
"What is it?" the Green Lantern showed interest.
"I got this job to do, for which I can use all the help I can get." Potter explained, "If you help me, I will be witness to how you use that ring, which can help in our ultimate decission as to whether or not we will allow you to keep the ring or not. How does that sound?"
"Wait, are you going to do something the Ministry wouldn't approve of?" Eliot asked.
"What other choice do I have?" Potter asked in return.
Eliot had to think about this, and realized that if this Lantern was no longer in custody, that would be a load of weight off his shoulders, so he decided: "I'll go check if nobody's watching."
"Wait." Potter stopped him, "He must agree first."
The Green Lantern was thinking this through. On one hand, it could be a trap, so to lower his guard, so they could take the ring away whenever they saw an opening. On the other, this may an opportunity. This way he could prove he doesn't want to use the ring for any evil purpose, so these people would finally stop following him. Still, he couldn't take any chances. With his technical ring, he created a forcefield around him, just in case.
"This better be worth it." the Green Lantern spoke as he looked back at Potter.
