He was obviously a noble acting as a commoner, he recognizes the sword and its crest plus the way he talks... He was very suspicious so I’m not surprised. His golden eyes told me what I needed to know. Like I don't think the author will introduce more families soooo, Parlam it is. This forced/rushed friendship also is a big hint.
I'm a bit disappointed that Canaria and Cesar were so reckless and foolish with a stranger in the Parlam's lands. Damn, Ricardo probably learn more in three day than the Empress in 20 years...
