Hey I'm back! Talking about the climax of the story! I'd say it's when Dionysus finally overpowers Pentheus and he's killed by the maenads. It's like the clash between the two, the wild mirthful god and the strict, harsh nonbeliever. It's drawing the story of these two opposing forces, these two opposing beings, to a grand closure. The death of Pentheus was inevitable though because of Dionysus's mighty power, which he uses to not only kill Pentheus but to ban his family therefore gaining praise in Thebes. That's the climax, good bye thanks for listening!
