Batman's limping.
He's walking firmly on both feet but to Superman's eyes there's a minute shift in weight, a microsecond of pause. He almost uses X-ray vision but Batman's spine stiffens as if he can read Superman's mind. Kal-el decides against it.
Sighing he rubs his forehead and lets his own legs drag. They'd been fighting against magic. His body is peppered with slashes that bleed.
When Batman steps back, contacts the Watchtower to take them both straight to the infirmary, Superman easily hides his smile. Hiding shock at a subvocal "Thank You", while medical staff checks them both over, is more difficult.
