Nerissa explained what Mirel told them.
It didn't go as Leandra thought it would.
As soon as Lucivar stabbed her, a battle against Master Tobias started, which resulted in clear defeat on their part. Even Lucivar was helpless. It was unclear whether he couldn't quite go all-out or not, but he lost that battle.
Mirel thought it was over, but then out of nowhere, Lucivar emerged from among the rubble.
"He didn't see it with his own two eyes, only from what Lucivar explained to him," Nerissa explained, fidgeting with her fingers. "It was confusing to understand, but basically, Master Tobias—and Lucivar had another fight nearby. And as it turns out, the 'Lucivar' who lost was not the real one. It was a fake."
"Lucivar had used this power before," Ravenna added. "I marked him with my Predator Oculus ability; he knew about this, and the night before the birthday party, I saw him split into three. But I can't say a thing, so I can't tell you guys."
