I always assumed they were. They are not Watching them dance and in interviews I thought of the Canadian pair couple who tied for a Gold in 2002 and got married right after. I just assumed with the amount of touching they due at one point as late teens it would translate into sex. Although its probably for the best they aren't when it was said they danced together since 4 years old my mind instantly thought of the novel The Pact. The Pact was about two teens in love that knew each other and were friends since they were babies, it didn't end well. The novel is fantastic.
