The emotional arc moves Lena from control to surrender.

She begins needing to fix everything alone — that is how her guilt expresses itself. Each act strips away one of her defenses. The midpoint is the first time she asks for help and actually means it; it should feel like a wound reopening, not a triumph.

The crew's arc mirrors hers: a group of people performing trust learns to actually trust. Theo's lie is the emotional landmine — when it surfaces, the betrayal must cost something real.

The climax earns its hope. It is not handed over for free; someone pays for it, and the reader should feel the price before they feel the relief.
