It had crossed my mind to be honest. Tonys trying to gain Christopers trust back. And when Chris says it wouldn't matter anyway i get the feeling even his thinking i can't go back to Tony and say I think your lying. He'd already told Tony that he's love for him was under question for the way he handled the jackie jr thing. So they are both at the crossroads of making piece. If he lied it wouldn't be shocking just as it isn't to the character Christopher.
