<P> As Abby Deveraux 's best friend , Chelsea is a bad influence . She encourages Abby to smoke , drink , and lie often to her mother . She also has a few driving incidents , including having her license revoked . Of course , the most serious accident results in the death of Zack Brady -- her half - brother , whom she hits while she is text messaging and driving simultaneously , thus incurring the wrath of Hope Brady and half - brother Shawn Brady . </P>
