This is the final part of my Hidden German Whisper series. Maybe there will be a second season?

Part 1: Warm Up

Part 2: Follow Up

Part 3: Sum Up

Part 4: Trinity

Rules:

• Normal Sudoku rules apply: Place the digits 1–9 once each in every row, column, and 3x3 box.
• Dynamic Fog: The grid is partially covered by fog and correctly placing digits may reveal more clues. No guessing is required or allowed.
• Thermometers: Digits strictly increase from the bulb end of a thermo.
• Renban: Digits on a purple line form a non-repeating set of consecutive digits, in any order.
• Region Sum Lines: Box borders divide each blue line into segments with the same sum.
• Lines mentioned above may only move from center to center. They may overlap only at endpoints, but never cross. Renban and Region Sum Lines cannot overlap with their own kind (even at endpoints), so each is a single line.
• Region: All (and only) the cells connected by Lines mentioned above belong to the same region. Digits MAY repreat within the same region.
• Hidden German Whisper: Hidden beneath each region is at least one German Whisper line. Each German Whisper line is at least THREE cells long, and lies entirely beneath the lines mentioned above. Adjacent digits along a German Whisper line must differ by at least 5.
