Someone with a power to timetravel? [ That is pretty cool. He tilts his head, fork poking at something in his bowl. ] .. Mutation?

[ 'Mutation' has always sounded odd to Severus, and like something negative - the slight uncertainty shows in his voice. He's not sure what to call it. ]

I don't think any construct of nature is good or bad. But I also don't think anyone will know for sure without seeing what's on the other side.
