@JacobDuBois8 Well, actually I don't know if Issac will be able to actually confess it right then and there in episode 5. In other stories, the chars are comfortable with it because they had a lot of time with the Z-team. Here's the difference with Issac.
1. He's had roughly a month of time with the Z-team.
2. Issac is borderline insane, the chip and the adrenaline lock are the only things keeping him from having a Batman who laughs ah insanity breakdown.
3. He fears what will happen to him if they find out about the chip, because it's the only thing that keeps his body from collapse and even he doesn't know if he'll survive withdrawal from the chip, meaning he doesn't want any people knowing about it, especially since he's with Prism and doesn't want to burden anyone, if that happened it'd likely boost the 'inconvenience' image he has made of himself.
