Corpse Girl dropping a cap and punching Legion

Madelyn let the cap drop from her hand. It hit the ground and Legion’s head shifted to glare at it. The dead eyes went wide for a moment. “The ****?” he said.
“See?” said Cerberus. “He saw that.”
“That’s the big guy’s hat,” said the dead woman. “Where’d that come fr—”
Madelyn slammed her fist into the ex’s shoulder. It wasn’t a great punch, but Legion staggered back a step and spun around. “What the ****!” he shouted. The ex reached up to probe its shoulder with its fingers. It glared at the heroes.
“He can feel getting hit,” Madelyn said, “I just don’t think he knows I’m doing it.”
“Maybe it’s because he doesn’t know what to look for,” mused Cerberus. “He can’t prioritize you because he doesn’t know you’re there. It doesn’t even seem like he hears you.”
Madelyn leaned into the ex’s ear. “Hey!” she shouted. “I’m right here!”
“Hear who?” said Legion. The dead woman looked up at Cerberus, then past Madelyn to the roof of a nearby building. “Stealth up there somewhere? This her idea?”
