Tony has to tell three of the four most important people in his life what he just found out, one of whom is also one of the most important people in Peter's life. Once he does tell them, though, the ball starts rolling to bigger and better things. Things he would have never even dreamed of a year ago. He's happy, the happiest he's been in a long time. Or Tony tells May, Pepper and Happy that Peter is actually his biological son.
