Hollyoaks star Nicole Barber-Lane has said that Myra will believe she is going to die when Doctor Browning confronts her with a gun.
Viewers will see Myra fall into water after being shot by Browning (Joseph Thompson) in an explosive episode next week.
Barber-Lane said to All About Soap: "There is a bit of a chase, and they end up at the docks. She sees him with a gun and thinks, 'This is it!'
"She's worried about what he has done with Mercedes and she just wants him to calm down. But obviously it doesn't work.
"Browning is a psycho and as far as he's concerned, he just has to end this torment that he believes she's responsible for."
Barber-Lane also revealed that they filmed different scenarios for the way Browning shoots Myra.
"We filmed the moment when he shoots Myra in two different ways - one was where Myra kept her cool. You know how you get so scared that you actually seem very calm?
"Then, in the other, she was hysterical. I'm not sure which one they are going to go for."
It was announced earlier this month that Barber-Lane would be bowing out of her role as Myra, as a result of the explosive shooting.
Speaking about her exit, the actress said: "I'm sad to be leaving all the people at Hollyoaks. Everyone there is so dedicated and passionate about what they are doing. It is a great place to work."
