For R+J I think it will be a character question because the past 2 years were themes,
maybe - mercutio or romeo, could be something like to what extent is benvolio shown to be a peacemaker or to what extent is mercutio shown to be a provocative character.
For J+H I have a feeling it might be something like knowledge and power as a good/bad thing, or maybe how good/evil is presented - or How is Hyde presented in the novella.
For AIC - I feel like it could be a character question on Mr Birling, Sheila or Edna. I feel like there isnt going to be a theme question but one of the statement ones.
