Trinity Margot Kwan first appeared when she was born onscreen in October 2014. Following a head injury in late 2013, Chris Warner (Michael Galvin) decided to have another child and recruited Grace Kwan (Lynette Forday) to mother it. Once Grace became pregnant, she fell in love with Chris but to protect his wife Rachel (Angela Bloomfield), she decided to flee the country. Grace's best friend Brooke (Beth Allen) pretended she had suffered a miscarriage while Grace moved to Australia. Chris later discovered the truth but kept it from Rachel. In October, Grace ended up giving birth to her daughter while visiting Fiji and she and Chris named her Trinity. Trinity and Grace moved to Australia in December, but were visited many times over the next year by Chris and his family.
