Rex and Edward went inside the training room,
Edward then explained to him about his meeting with Hans, the day of the delivery of the second spellbook.
While listening to Edward, Rex's expression didn't change.
The stoic look on his face is unmoving, and even Edward look at him in confusion as he explains the meeting he had.
"He's being sarcastic about the spellbook, and I just feel like he's up to something", Edward said.
Hearing this, Rex fall into thoughts, 'They should've caught up about the rigged spellbook, It will confuse them knowing that the second one is not'
After thinking about that,
Rex nodded his head as he's hearing Edward's explanation, "It's okay, call Ari to meet me at my room tonight"
Instead of leaving, Edward still looks at Rex with a troubled look.
"We're talking about Hans from the Atkins family here, this is not something light and he might do something", Edward added.
