After arriving in the palace, Kylo had to excuse himself. He has no issue with people being festive and all that, but he was concerned about Chartlon.
When he went outside donning plain garbs so as not to give away his identity, he heard the song 'for the first time' and it pissed him off.
When he received the invite, he was shocked. Whatever happened? He thought. He tried calling Charlton's mansion. When he could not reach him, he asked to talk to the butler who thankfully recognized him. Anyhow, that was how he learned of all the events that transpired to Charlton's family.
It was horrible, his father was sentenced as a criminal and Charlton was sent somewhere to find rebels at who knows where. Then, this woman who supposedly loved him was off to marry Geoffrey only after a month or so.
