I have a scene where my MC discovers the hidden mobile phone of one of his multiple personalities. He manages to unlock it accidentally purely by muscle memory, but he won't be able to do so again - that was just a fluke.
Yeah, I know. Stick with me
This phone is absolutely critical to the MC discovering the truth regarding that specific personality. Specifically, he looks at excerpts from three text conversations in order to advance the plot.
He then puts the phone down "because he doesn't have the heart to read any more" after discovering a betrayal.
This feels flimsy. I wouldn't do that. I'd keep reading. I'd go through all the texts, internet history, emails, anything I could find if I thought I needed to. But for the sake of brevity, he must turn the phone off.
Why would he do that?
