Ajani came to Zendikar because he believed the former evangels could understand one another in ways their uncompleated allies could not. He had retained his spark and had been restored through the work and sacrifice of friends. That support gave him a model for healing, but it also made his offer sound effortless beside Nahiri’s solitary recovery.
Nahiri refused to become an instrument for Ajani’s atonement. She wanted him away from Zendikar and read his persistence through a lifetime in which planeswalkers had repeatedly brought danger to her home. Ajani, grieving Jaya and the acts performed through him, heard her anger as another refusal to face their shared responsibility.
Their argument exposed why surviving the same violation did not create automatic solidarity. Compleation had exploited traits already present in them—purpose, protection and certainty—then sharpened those traits into weapons. Afterward, the same qualities could still prevent them from recognising help that did not arrive in the form they needed.
