Please feel free to have someone read in the lines of the other characters, but leaving those lines unspoken is fine.
JANE: Alright. I’ll come and help you then.
STEPHEN: No, you stay here in the warm. Someone needs to look after Flora anyway.
FLORA: No someone doesn’t! I am perfectly capable of looking after myself. Probably a hell of a lot more capable than with you dopey pair trying to navigate me around. A job shared is a job halved, so both of you hop it and stop haunting me.
HYNES: There isn’t a person in this room who isn’t a suspect. Including me.
FLORA: Jesus, Mary and Joseph! He’s the killer!
HYNES: I assure you, Mrs Flora, I have not committed a murder.
FLORA: Thank God!
HYNES: You believe me?
FLORA: Well- I thought I might.
HYNES: Don’t. Why would you take me at my word?
