Antony and the Young Caesar

Antony was under obligation to give every romance 75 drachmas, which is the same in greek currency. When octavian tried to dedicate a golden chair in honor of his father by adoption caesar, antony threatened to haile him off to prison unless he stopped trying to win popular favor. This might not just be antony trying to get one over octavian and say, i'm the one who's really in charge. Is a proper grown up here?
