Okay, for how calm he was over the journal to Marnie, Mycroft was pretty worried about this whole marriage quiz thing. He's been expecting something like it, so he'd come up with a plan. Multiple plans actually, but this one to begin with. Marnie coming back had certainly been a problem, Mycroft had thought it would be a short term thing, where whomever he married would just leave, but well, he couldn't think about that, he'd focus on what they had to get done. Except that Marnie was not here, she had other plans, and really, what was that all about? Mycroft seriously did not want to get into that train of thought, so he started reciting the fact pattern over and over again in his head, while throwing a tennis ball in the air as he laid back on his couch.

Of course he knew everything about Marnie that the ministry had, he had a copy of her file laying in front of him on the coffee table (he hadn't been stupid about getting married to some random woman) but there were bits missing, like about Marnie's childhood, her favorite foods, things that a file couldn't fill in. But he could make sure he knew at least ninety percent of things. That was all that mattered, getting to ninety. There were other plans, that Mycroft would set up - he just hoped that whatever room they were interviewed in, it didn't negate portkeys.
