Curate, connect, and discover
In "Turnabout Sisters" of "Ace Attorney", there's a moment where Redd White punches Phoenix in the face as a "I can hit you for no reason and you can't do anything to me" thing, and then they both show up to court the next day.
And... look, maybe it was a really shitty punch, but I prefer to imagine that this did leave at least a serious bruise on Phoenix's face. The screen temporarily goes black, White is wearing a bunch of heavy rings on every finger of both hands, and White is a murderer and a blackmailer whose crimes are on the edge of coming to light. White has Phoenix arrested for the murder immediately afterwards, so Phoenix would not have had any opportunity to cover up the injury, leaving the entire court to see what should at least be some really ugly bruising.
Phoenix is having the worst time here, but Edgeworth must be GOING THROUGH IT. Because now he has to prosecute Phoenix Wright of all people for Mia Fey's murder, when he's already been an ass throughout this trial and he knows it, and everything about his key witnesses here is incredibly suspicious (especially if he is at all aware of just how influential and corrupt White is). I would love to be in Miles' head the moment he mentally matches Redd White's smug expression and gaudy rings to the ugly bruises across Phoenix's face.
Now THAT'S an "oh" moment. Not a romantic one, in my opinion, because it's too early. But definitely something that could have unconsciously or consciously flipped a "oh, this is the part where I tear you to pieces" switch regarding Redd White.
