Series 10 Filming & Behind the Scenes

What do you all make of Sam Vincent's tweet that there were tears at the read through for ep. 6? "Spooks Ep 6 readthrough was great. Laughs, gasps, tears, cake, and pats on back for lowly writers from the bosses & lovely cast. YAY!"
Is that normal for a final read-through of the season, or does that mean it's the last episode ever and one of our beloved characters like Ruth or Harry dies? I hope not!!
