Smoke does not affect Servants in the same manner it does to people, partly because they are Spirits in flesh. Saber saw her fall due to the smoke, but she was too far away to be caught, even if she sped up her wings. The strong wind makes it trouble to navigate. She lands as fast as she can when she does find her, crouching beside Noire to give her a helping hand.

"Can you breathe?" she asks, reaching out to pull her up and to help her to move somewhere away from the ash and smoke range.
