Theo was less concerned with the wedding than the marriage, and most important was getting Andromeda loyal to them rather than to Bellatrix. Thinking of what Stephen said he tried to find a compromise. If Bellatrix wanted her to stay at the ministry she might not be willing to let her work elsewhere.
"If she can't leave the Ministry, there are always options," he said. "We lost plenty of people in the Department of Mysteries, and if research is what suits her then we can arrange something." It was the largest research facility in the country after all. "If she can leave the Ministry then we can see what we can find for her, possibly something tied to St Mungo's. In either case it would be good to keep her close to the family." Slowly shift her loyalties. It wasn't as if he wasn't spied on at work anyway, he could live with another set of eyes if needed.
