"Well, he's apparently been treating Ruby and Angus rather badly, including not being so very charitable towards Angus on the mission. Their contacts in Romania is a couple that is the current generation of a family that has been close to the Donohues because of Edward's work for at least two generations, maybe more. When Angus was a boy the Romanian family was a large one--eight children--all boys but one. The youngest was girl that was Angus's age. By the time Angus had reached seventeen, he and the girl were romantically involved, and they were together in a physical relationship for four or five years. They broke up when Angus was 22 and he went so far as to introduce her to a Romanian mate of his. The girl and the Romanian mate got married ten years ago, and they now have three children of their own. Angus doesn't have any romantic feelings for the girl now, and they trust Angus with their lives. They even call him their brother.
"I was the one who chose them as the contacts for the mission because they live in the village at the foot of the mountain and they run a waystation for wizarding lightworkers. The waystation goes back generations. Both the man and the woman are good guides, top notch fighters and excellent mountain climbers. However, Jessie hasn't been able to let it go. He's been making things even more miserable than normal for Angus, not being able to trust that he can be around them and betray Ruby. When Brian asked him what his issue was, he came out and said that, basically, he needed to protect Ruby from Angus because Angus isn't good for her because he hasn't married her and impregnated her already. So far as I'm concerned, Jessie's gone entirely too far. Angus Donohue isn't perfect, but loyalty is one of his strongest traits. He would never, ever betray Ruby. He loves her. The house and the plans they've made should be enough evidence of that. They don't need to be married to have children--when they're ready, and not before. But with as fresh as his parents' deaths are in Angus's mind, the last thing he needed was anyone else who believed he was a tosser and not good enough. The hurt and the damage he might have done to Angus is not something I can let simply go unanswered to."
