"You know, he changed a lot in a year. He went to a summer training camp being a boy and returned already an adult. We always talked to him about Katia: "Serezha, she is a very little girl, you don't have to be shy - help her to carry things and take care of her... If she'll injure her leg or something else, it's your common fate, so don't pay attention to anybody making fun of you." And well it went. They were friends, not really close ones. Everything happened much later... They were always together... Felt each others every muscle..." (Sergei's mother, Anna Filippovna, from "Broken Ice")
