Armando has to consider the source of the damaging flames, in The Architect’s Guardian, Chapter 45. Here’s an excerpt:
Armando froze, he wanted to help but he knew that he’d be ineffective. Sunja was finally able to eliminate the flames but not before she’d suffered significant damage on her face and arms. After taking a deep breath to calm her nerves, she focused and used her powers to begin to heal from the burns. The charred flesh on her arms and legs renewed itself and knitted together before Armando’s eyes.
