#regular cast

I think the promotion to regular/more main is determined by the plot. harry and may are probably involved in athenas plot in a more significant way now that bobby is gone. may was a dispatcher. they got their own storylines in the past. I can see it more easly with may than harry. harry maybe will try to be firefighter I guess. karen is in the plot only through hen. her work is not related. now that they are done adopting hen family life might not be as much of a focuse. also, tracie has many other projects. I love josh but all he really does is show up on dispatch from time to time to give advice. they could involve him more in the plot but that will mean alot more time showing dispatch or showing less maddie/may on dispatch. notice how may on dispatch meant less/no maddie on dispatch. they could very easly give ravi a bigger part in the plot. I think the main "problem" is ani availability for filming, we know he has other things going. I think with may they waited for corinne to graduate otherwise it would have been done even before. they could come up with ways to make all of them regular, but chose to focus on may and harry. I don't think they could promot all at the same time, the plot will be even more of a mess.
