What's the dialogue tag you would use when a person is trying to back up a claim they've made? e.g "I knew a guy once threw himself off a sky-scraper.' Tom threw his head back and laughed. "You're so full of shit, Pete." "It's true," Pete said (I need the tag that goes here) I've used 'defiantly' but I'm not convinced that's correct. I know it's not 'defensively' that I'm looking for either. There's one word in particular I'm looking for.
