Delivered in the tone of voice that indicates it's a question for more information as much as a statement. There's really only one she Scar can be assumed to be referring to, if not otherwise specified. His tangential involvement with the homunculi is now a great deal more rooted than it had been, 24 hours ago. He prefers to keep their dealings at arm's length. It's better for the peace, that way. Better for the lingering bad feelings.
