Leonel had known for a very long time that Orinik was the one that had spread information about how he had gotten his Amethyst Token.
In reality, Leonel didn't care much about this alone. After all, Orinik was telling the truth, he didn't spin a lie. Leonel had, indeed, used his connections to gain his Token.
However, the matters of back then were quite a bit more complex than others knew. While Myghell hadn't used the Innate Node during their battle, Leonel hadn't used his Ability Index. When Leonel's Ability Index was active, he could even defeat Sixth Dimensional existences while at Tier 1 of the Fifth Dimension.
Of course, those Sixth Dimensional existences couldn't possibly match up to the Sixth Dimensional existence of the Void Palace. But, Myghell hadn't been in the Sixth Dimension back then either.
