Lucius had been standing by the window in the common room earlier today, when Moody had shoved a note into his hands. Lucius had raised a brow and was about to ask what the note said but Moody had walked passed by then. Moody had asked him to come to the seventh floor by a specific tapestry, the tapestry was a depiction of Barnabas the Barmy and Lucius knew that only meant one thing. Lucius decided to ask what Moody wanted, well only one way to find out.

Lucius decided to go meet Moody on the seventh floor, by the tapestry. Lucius had found the room just two years prior, he had been searching for somewhere, where he could practice and perfect his spells. He had walked passed that wall a three times when the door had appeared to him. He had found the room by accident he honestly didn't even know it had existed until the door appeared to him, his father had told him everything about the castle but hadn't mentioned the room, but that could be because Abraxas never found the room. 

Lucius thought maybe Moody wanted to practice a spell or two with him, there were a few reasons for that, but he could understand why Alastor chose him, they were in the same house and it was easier to contact someone in your own house without raising any suspicion than it was when contacting someone from another house. Lucius had already joined the death eaters the year earlier, but that was not because he wanted to join them by choice, his father had pressurized him to do so and wouldn't be surprised if his brother Nicholas was forced to do the same. Lucius wasn't very great at using Curses, he was only good with one of the Unforgivables, the Crutiatus Curse.

Lucius stood right behind Alastor on the seventh floor, "So, why are we here? Let me guess you've found the room?" he casually asked.

Lucius raised his own brow at Alastor, he hadn't expected he'd find the Room for one. Lucius wasn't sure why Alastor had asked him to meet by the Room of Requirements, he'd guessed Alastor must have found the room and thought that the fellow Slytherin might have wanted to practice and perfect spells, like Lucius still did many times with a friend or two. Lucius's eyes widened when Alastor revealed he wanted Lucius to break the law to help the other boy build immunity to an unforgivable. Maybe Alastor wouldn't get into trouble for asking him to do so, but Lucius could certainly get into trouble.

"I know it is the perfect place to practise spells and do quite a few things alone or with other people, neither of us are the first or probably the last to find it" he shrugged, watching as Alastor's eye whirling around but he didn't make comment on it. What Alastor said next made Lucius widen his eyes, "Are you serious? You want me to cast an unforgivable on you?" he asked shocked, Lucius raised a brow at the explanation he got, "The... you are aware it's called unforgivable for a reason? Cruciatus curse... it hurts like no other pain you've probably endured before and... I speak from experience" Lucius shuddered at the memory of being subject to it. "Yeah well that's easy for you to say, you won't get into trouble for asking me to caste a unforgivable on you but I will be in trouble if I caste it on you. So tell me, if I do agree to this what's in it for me?" he questioned, Lucius didn't want to get into or want any trouble.
