Does anyone have any amazing tips on how to escalate tension in a dialogue scene? I have an act climax that I want to take place during a dinner scene, things need to heat up enough that the characters hit a breaking point, but I really really really need to keep most if not all of the scene from being on the nose. I have three characters that have reached an impasse with their dynamic with one another, but for most of this scene they are not going to be willing to voice that, so I need to build the tension with indirect dialogue.
Hopefully this question isn't too specific.... I feel like this is something that I should be able to do fairly easily, but I typically have my emotional script moments as strict visuals.
