I see that Jack is setting Adam up with this new scheme. First; he calls the forger using Adam's phone (claiming he left his in his car); then he gives the forger the name 'Victor' as the contact; then he begs off when Adam meets with the forger, so the forger has never met Jack and Jack is not involved. It will look as though it's all Adam's idea for revenge while Jack sits in the background, watching it all go down.
Also, now that Heather has seen Adam together with the forger; when all this comes out and the truth is found out about the forging, Adam and Heather will be toast because he lied to her when he told her that he didn't know the forger and that he had just met him at a job interview. Adam will be on the hook for the entire forging scheme himself and Jack will be in the clear. We might see Adam go to jail for this one.
So what do you think?
