-You gotta cry before you sing
Andromeda Tonks never really fancied Remus John Lupin. While she was glad that her daughter was happy with the man and that the man was equally content with Nymphadora, her daughter could have done a lot better. Then again, they were in the midst of the massive Second Great Wizarding War. You take what you can get don't you?
Of course that philosophy went down the drain when she found out that she was expecting a grandchild. There was nothing wrong with that, if it weren't for the fact that Lupin had totally freaked out, locked himself for hours afterwards and promptly Disapparated out of his room that evening.
Nymphadora was a mess, although she didn't dare show it. But Andromeda knew, in the early hours of the morning, the witch would sit by her empty bedside and stay awake until sunrise. Nymphadora would never admit it, but she cried some of those times during that wretched week. The drying tear tracks were enough evidence. Ted was more blatant about his disapproval but Andromeda kept quiet. Her daughter should be given the chance to grieve quietly first.
Lupin came back eventually, after seven days. Apparated, much like a gentlemen, right onto the front step; Andromeda was glad that he had the respect not to let himself back into the house. The moment Nymphadora opened the door, she leaped into his tired arms. Tears collected in the corners of Lupin's eyes, the ghost of 12 Grimmauld Place written all over his face. The ghost of a rather painful argument. The couple retreated into the upstairs room and Andromeda, despite her not-exact fondness of the werewolf-wizard, knew that through all their mistakes and follies, the two would make it out okay.
