Before arriving in Erinsborough, Sebastian changed his name to Will Griggs. Will moves into Number 30 Ramsay Street with Frazer, Pepper and Rosie. Rosie becomes attracted to him instantly and writes about her feelings for Will in her diary, which Will sees. Rosie sets Will up on a date with her sister, Carmella Cammeniti (Natalie Blair), which she accepts. Will and Carmella have a good first date, but Will refuses to talk about his past. Will begins receiving strange offerings, such as keys to a new car. Will, however, rejects the offers. It is soon revealed that he is the heir to a large fortune, including a 2% stock of Lassiter's. Paul Robinson (Stefan Dennis) discovers this, along with Will's real name. He promises to keep Will's secret, as long as he votes against the Timminses at the next board meeting, as Paul cannot purchase the stock from Will.
