Hohenheim snapped up, staring at the Xingese prince as he kept talking. "Ed figured out what Father did, what he's after, and what the Homunculi are made of. He used some of Envy's souls to open a portal out of Gluttony. He's probably told Al about it."
"But knowing it and seeing it are two very different things," Hohenheim added.
Ling nodded. "Ed's seen what's inside us, what makes us so powerful." The prince stared him in the eye, "He's got every right to be this torn up."
"Between that and his hatred of me, I'm surprised he turned down my offer." Hohenheim smiled as he sat back down. "He's as tenacious as his mother."
"And as annoying as his old man." The homunculus turned around and walked away waving. "Later Pops."
