Riddler is standing by the door and opens it as soon as John knocks, gesturing him in. He looks like hell. "If they were sex toys, I'd tell you to go home and I'd go to yours. He's already recorded Ed having sex, I have no plans to add to his collection or give him ammunition to get us in trouble with the officials."

So far, it seems to be the unspoken rule. Tim could probably get Ed in trouble with the system. Ed could report Tim and get him in trouble with officials. But they both knew that they would not be bringing the despicable government and SIN guards in on this. This, this was Gotham business.
