"I meant that I learned how to do it from a book," Luis said.
"A book?" Orah said.
"Yeah," Luis replied with a nod.
There was nothing wrong with telling Orah that Nova was an Angel but Nova had made it clear that she didn't want anyone else to find out about her true identity and Luis had to respect that, he was just glad that she wasn't trying to go after Orah just because he was a Demon.
"What book?" Orah asked.
"It's a special book, I found it at the museum on the highest floor in the museum," Luis said.
"The museum?"
"Yeah, you see that tall building over there?" Luis said, pointing toward the museum.
"Yeah," Orah said after spotting the building which wasn't that hard given the fact that the building was the tallest in the academy.
"That's the museum," Luis said.
"Okay, but you know your aura isn't suppressed right now, I can still smell it on you," Orah said, giving him a sniff.
