[Darkleer makes sure to encourage his little stolen pony to canter somewhere else so that he doesn't nicker near his strategically placed SFC. Then he turns it on.]

What he first said was that a troll should speak from his heart. He shouldn't overthink it, just speak.

Then he said that if the words have already left his mouth, then there's no point in worrying much about it because they've simply been said already. If it's important, one of you will recall it.

I hope that assists.
