So I am trying to write some dialogue where there will be a few lines where the girl screams. However after she screams a few times (perhaps 3) she stops using those lines and resorts to the other lines as well as the acceptance lines, which were unavailable until this point. What I am asking is how can this be done? I figure it probably has something to do with variables but I am not 100% sure how to do it. Could someone give me some advice/suggestions how to do it?
