thought Alf would become "a likely suspect" if anything happened to Penn. Nicole, John Palmer (Shane Withington), Miles Copeland (Josh Quong Tart), Marilyn Chambers (Emily Symons) and Sid Walker (Robert Mammone) were also named as suspects. Penn arrives in Summer Bay and Nicole is immediately attracted to him. They begin dating but Romeo Smith (Luke Mitchell) spots Penn kissing Hayley Doven (Bonnie Sveen) and tells Nicole. Nicole downplays it but is visibly uncomfortable with Penn seeing someone else. Penn later causes trouble in town when he frames Colleen Smart (Lyn Collingwood) for theft by planting several items, including his own wallet in her mobile home, leading to her arrest. He also creates friction by telling Nicole that Sid Walker still has feelings for her. Miles Copeland and Marilyn Chambers try to convince Nicole that Penn is lying, but she will not listen. Penn is then evicted from the Caravan Park. Penn apologises to Nicole on the beach and hides a syringe in the sand which pierces Nicole's hand when she places her hand on it. Penn takes her to the hospital to get checked out and comforts her. Nicole takes a HIV test and gets some anti-viral medication. While out at dinner, Penn admits to planting the needle but refuses to confirm whether it was infected or not. Nicole then finishes with Penn. Shortly after Penn is beaten up and hospitalised. Alf Stewart (Ray Meagher) is a prime suspect after a heated argument but is exonerated when Penn admits it wasn't him but some guys who wanted a ride. It emerges that Penn is the son of Tulip O'Hare (Kimberley Hews), a woman who Alf had an affair with in 1987, two years after the death of his wife Martha (Alison Mulvaney). Tulip was in love with Alf, but after Penn saw them together, he ended the affair and Tulip committed suicide by overdosing on diazepam. Penn blames Alf for his mother's death and he begins taunting him. He later disappears and blood is found in his hotel room, but no body. Several weeks later Penn's body washes up on the beach and Alf is the prime suspect after several witnesses heard him threaten to kill Penn. Alf is remanded in custody for six weeks and eventually released. Will Smith (Zac Drayson) reveals he stabbed Penn in self-defence and Daria Hennessy (Samantha Tolj) helped him dispose of the body.
