Lucius stepped smoothly into Severus's quarters and let his eyes adjust to the light and the interior. He turned, not having missed Snape's slight reaction to his comments.
"Come now, Severus. She did look quite, quite fetching in that outfit," and he paused as his eyes caught the other man's, "Even to me. She looked...positively pure in that attire. No one could really blame you. Your choices are rather limited here. I mean its her company or Pomona Sprouts, and I hardly think that woman appropriate at all."
Lucius smirked slightly, "I'd be talking about you two, just from the way she looked at you, Severus. You seem to have gained an admirer," and Lucius noted a chair and moved to sit down.
He changed the subject back to the team, clearing his throat before he did so, "Well, yes, the bunch didn't seem quite as unified as the other. That will change," Lucius said, with some confidence and force. He slipped the small vial out of his pocket, and extended an open palm to Snape, the treasure ready to be taken, "I thought you might enjoy this, to add to your wares. Acromantula venom, and please, do not ask me how it was acquired. That's my little secret."
