Aslan Is Acting Weird

From Rosie's expression, it seemed that the letter Howland wrote to Rosie did not contain any information about the girl's meeting with Prince Nicholas. 

Aslan seemed to be walking on the edge of a nearly cracked shell. He even sent a man to looked for information about Nicholas Bhaer. 

Nicholas Bhaer was the prince of the Oceania Kingdom on the other side of the Kingdom. He was the third son of the king, which meant he was not a crown prince who would become a king. 

Still... The man was a royal prince. It meant he had the same status as Rosie. He was a handsome man, so Rosie would have liked him. Apart from that, he had a clean record and Aslan couldn't find any scandals involving Prince Nicholas.

Aslan knew one day this would happen considering the king's sons and daughters were pawns to expand the political power of the kingdom, and Aslan used to think that he had no problem with that. But, why did he feel uneasy now?
