Old Luke didn't answer Finn's question right away and first, glance at Alvin for his approval.

Since this information was only known to 1st Grade Kingdoms!

He also didn't know why Alvin was bringing this boy with them, although he was curious, he didn't have the right to question Alvin's arrangement.

Ace also noticed this brief exchange and stay quiet while waiting for Alvin to decide.

Alvin nonchalantly nodded, his meaning was clear, 'You can tell him.'

"Brother you can't tell this peasant about this information!" Sofia was also watching this closely and when she saw Alvin giving his approval she instantly protests. 

'Is she jealous?' Ace pull an amusing face because he could tell this woman was not doing it just for the sake of secrecy. She was doing it for Alvin's attention.
