Aemond Targaryen was the definition of still waters run deep. The King's second son was quiet and silent, but when he showed his second side, things got dangerous. Sometimes it got out of hand and then there was big trouble.

Aemond sat on an armchair in his room, sharpening his sword. You, as his sibling, sat on another armchair and knitted.

You two don't need words to understand each other and enjoy the peace and quiet you find with each other.
