Anderson explained that Charlie will soon deal with a crisis of conscience in relation to her relationship with Brax (Steve Peacocke), which may also affect her career in the police force.
Brax will be connected to an armed robbery investigation, which forces Charlie to consider breaking the law to clear his name.
"Charlie makes a shock decision to interfere with police evidence," Anderson told TV Week. "This decision could ultimately undermine her credibility as a police officer and force her to question the career she's worked so hard to establish.
"Charlie and Brax discuss the sacrifice she has made for him. She's quite upset, and Brax reveals he still has feelings for her."
When returning to Summer Bay after a trip out of town, along with Heath and Bianca, their car accidentally hits Liam (Axle Whitehead) on his motorbike.
Heath (Daniel Ewing) takes the blame for the incident to avoid people noticing that Brax and Charlie were together.
"Charlie is angry at Brax over this plan to lie - even though she knows the consequences of telling the truth are monumental for all," she added. "She's also extremely worried about Liam's injuries and what this will mean for her future friendship for Bianca."
Anderson recently denied rumours that she is in a real-life relationship with Peacocke.
