"Crinem means lock in Latin, and because it is at the end of the spell then it can be assumed that it is in the context of locking in the meaning of the previous words and not in fact physical like a door." "Impressive." Tom stated, his expression stoic as always but his eyes gleamed as he appraised the tiny first year. "Indefinita, it is Latin for Unlimited and Indefinite so it can have a few different meanings in spell work, but paired with locking something and context of actions I would take it as unlimited and multiple." The boy continued softly, smiling and gaining confidence as The Dark Lord’s eyes widened in surprise and glee. "Arcana means mysterious usually, but in certain phrases in Latin can be used for Secret. With that information I would believe it is spell designed to keep secrets within groups unlike an Unbreakable Vow or Blood contract which can’t be between more than three people." "What’s your name?" Tom demanded. "Regan Harper My Lord." The boy answered diligently. "Related to Cassius Harper and Elizabeth Collins?" Tom asked knowingly. "Yes My Lord, my Grandparents." "Hmm, A Pureblood Slytherin and Muggle-born Ravenclaw, few years below me in school." Tom revealed. "Not surprised you have your Grandfather’s spell talent and Grandmother’s intelligence. You hear that Gibbon, Jugson, you are stupider than a first year whose Grandmother was one of those you insult." He taunted. "Yes, the spell I created is used for making it impossible for groups of indefinite numbers revealing a secret to those who are not under the same spell. You will never be able to tell the Wizarding World I am back or that Hermione and Hartford Riddle are my children being raised by me. You will not be able to confide in your parents and lie about what went down here. But be assured, when I make my returned known, I will be informing them of how you disgraced their names." The shaking boys nodded their heads in fear of their situation getting worse if they spoke. "Now, Hermione my dear, where is Hartford, he would’ve loved this but hasn’t made his presence known." "He took off after we were assembled here, he was worried about the red flame." Hermione spoke in a riddle as to not reveal her Brother’s secret Soulmate, even with the spell protecting him, it wasn’t her secret to tell. "But I locked the entrance way!" Severus said astonished, even though he knew by now to not be surprised by the twins. "The Slytherin common room has a Parseltongue bypass." Tom groaned. When he found his son, he may actually kill the boy.
