She looked at Viktor with concern when Yuuri described his injury. "Amnesia? That's alarming." And very unusual. It wasn't at all unusual to lose your memories of events immediately prior to a head injury--they never make it into long-term memory. But two years?
Michelle didn't know a lot about such things, but it seemed strange. Did he not want to remember his recent past? Or even--pretend not to remember it? She hated that such suspicions came so easily to her, but she couldn't avoid them.
On the other hand, she couldn't imagine what purpose such a subterfuge would serve. If Viktor and Yuuri were close friends, Yuuri would know most of whatever Viktor couldn't remember. And if Viktor didn't want to talk about his past, he could always just...not talk about it.
"Well," Michelle said, firmly squelching her paranoia, "with any luck you'll start to recover your memories soon. Amnesia seldom lasts long, I'm told. At least you have a friend here to help fill you in on what you've forgotten."
