Nobunaga gives off an epic rant when he finds out that Akechi Mitsuhide, the man who betrayed him, killed his son Nobutada and tried to have him killed at Honno-ji, is commanding the Black King's main army at Mamon Fields.
Nobunaga is visibly irritated at having to babysit the senile Hannibal. Then the aged warrior chuckles and shows him how to break the siege Oda's struggling with, not even bothering to speak. It takes a bit for the idea to sink in, but Oda's left stunned and wondering just how "senile" Hannibal really is.
