After returning from the dinner party, Luke didn't dwell on Nelson being set up.
He just added a simple reminder to the multifaceted system to keep an eye out for relevant information.
He wasn't the Chief of Department's nanny. It was fine to help out a little, but it was impossible to be at his beck and call.
If it were Dustin, Luke might be more serious.
Besides, Nelson was a sly old fox who had spent most of his life in NYPD. If he was still screwed over even after increasing his vigilance, it could only be said that he was incompetent, and he may as well retire earlier.
In any case, setting traps like this happened all throughout society. Even the president of the United States would be screwed over sometimes. A police chief like Nelson really wasn't a big deal.
Luke still had new abilities to study and develop, and his clone could start harvesting points at any time, so he let it go.
