Let me add an off comment here. I think there is general agreement among the actors, and the suits, that filming so far ahead is detrimental to the show. In an interview, or tweet, I think it was Vincent Irizarry (Deimos) who said that when the one month hiatus is over, he understands there was going to be some sort of change in the filming schedule.
Personally, I think this is why some of the show seem so disjointed or out of sync or something. Changing story direction/intent where they can. I felt that they already deleted a few scenes between Rafe & Hope. In fact there were several scenes that are known to have been excised....a kiss between Rafe & Hope, a conversation wherein Hope asked him how he felt about her returning to the force, if it would bother him. We all are aware Hope was very suddenly "back on the force", with not a word, hint, conversation, etc. It is a bit disconcerting, for sure.
I like that they are good friends...and to tell the truth, though I think it would be a mistake, I could handle a romance between Rafe & Hope better than I am able to handle Brady & Theresa being together. And Deimos with Kate is even worse.
