Didn't all of this happen after Sylvanas blew the horn and initiated the retreat + her dark rangers flying above them? I remember Parqual approaching Calia and then Calia trying to persuade Elsie but Calia shouting started after Sylvanas made her turn if I'm correct. I just read it 3 hours ago but I'm not so sure about the sequence it took place.
And where was the Council involved... at all? Again, who was defecting at first place? Emma's three sons and Parqual? I mean seriously, those 4 guys are a threat to Sylvanas? Wasn't even clear if anyone besides Parqual really tried to defect before Sylvanas went full mass murder.
