Silas George Harper {3} and Susan Pevensie Harper {15 mo} are two of Huck & Sonny's siblings, cousins of Max, Yale, and Cliff. Silas is very shy, he is an introvert by no doubt. He hardly ever talks, not even to his parents or siblings. His best friend doesn't stop talking, so he never has to say much. Susan is a bit whiny, but her parents are hopeful that she'll grow out of it.
