Erran had seen Simms briefly before the trial, and was prepared to half-ass this thing with all his might. Lionel Hutz, attorney at law. He figured that he had to put on some kind of effort or their overlords might decide the guilty verdict didn't "count", but he also didn't want to badger Juno in any way. Or help Simms get off, really. Which would have made him a very unethical lawyer, so it was a good thing that he wasn't one. He hadn't even seen a good courtroom drama flick in a long time.
He figured that he probably had to make some effort to ask questions and build a case, so when Juno finished her testimony, Erran said, "Defence has a question for the prosecution's witness. Was Mrs. Lila Simms present during this encounter with the defendant?"
