Which of Colleen's friends helps her most in her time of need in the novel, When Ghosts Come Home?

Danny, Colleen’s best friend from school, is described as fun and flamboyant, but also (in contrast to Colleen’s gossipy ex-girlfriends) kind and non-judgmental. Danny only features in Chapter Ten, but he contributes useful information about Frye, as well as helping Colleen in her time of need.
