[he carefully moves his hand back, then, setting that candle upright on a nearby bookshelf so he can take the handle of that dagger, taking a few steps back from Discord]

Thank you. I hadn't noticed. [his tone is absolutely venomous and accompanied by a glare similar in its intensity. Salieri sucks in a breath, setting the dagger down on a table, turning his back on it and putting himself between Discord and it as he pulls out a handkerchief, wincing with a hiss as he presses the scrap of cloth to the wound to stem the flow]

That is what happens when you grab a knife of some kind by something other than the handle. I thought you would be aware. [there is absolutely a simmering anger in his tone, and boy, if looks could kill, well...Discord wouldn't be dead, but he would certainly be at least out cold on the floor]

Now. Start from the beginning and do please try to explain to me what on Earth you were thinking.
