In this week's Holby City, Sacha plans to pop the question, but Essie is shocked when she learns her cancer has returned.
It was hinted in Holby City's spring trailer that Sacha is going to propose to Essie and his plan comes as soon as this week.
With Essie's ex-boyfriend Ben gone and the Isla situation seemingly sorted, it seems like it's the perfect time to pop the question to Essie.
Sacha soon lets Dom in on his secret but swears him to secrecy.
After spending the last few weeks at each other's throats, Dom realises he doesn't want to see Essie celebrate her engagement without him.
He swallows his pride and wants to put the past behind them; meanwhile Sacha encourages Essie to do the same.
As they both accept their wrongdoings, they agree to bury the hatchet and move forward.
However, it's not long before Essie is hit with some devastating news.
Essie goes for her six-month check up. Not wanting Sacha to worry, she asks Dom to be by her side during her appointment.
But unfortunately, Dom spots a new tumour on the scan and breaks the news to Essie, who is understandably worried.
What's next for Essie?
It was revealed in the Holby City Spring trailer that Essie's cancer would return.
It was also revealed that Fletch would also be diagnosed with cancer, marking the beginning of a difficult few months as the pair face the life-changing news.
