Hm. I don't think that's exactly what we're looking for here, actually. You are not shy about your knowledge about poisons, with is also part of one culprit profile, so I am not sure why you would hide your injury - even with accusations possible.

I also think... depending on the cut, it would not be half-healed in a day and a half. At least, not without the use of a potion. But why would a potion be used for a simple cut, unless it was necessary for something else that came after Wednesday? It was established, I think, that someone fought Lord Norton.

This is not limited to you, Lord Moriarty. Some others have used elixirs and potions, too. Myself included.
