Seeing Chris as her knight in shining armour, she quickly fell for her saviour and did everything she could to help him in his mission. But with Chris gone, how will the fragile Syren cope? Without Chris' guidance it's up to the others to continue integrating her into the team - and trying to find out why the villainous Dr. Parker was so interested in capturing her...
