C'mon man, don't even pretend like this is just a legality question.

YOU ARE A FLIGHT INSTRUCTOR NOW!

YOU are the one there making the decisions, you're no longer flying under the umbrella of someone else's CFI. Do you really want to be in charge of this flight with it in the back of your head that you havent done a night landing in 4 months? This, as well as all the decisions on this flight, will be YOUR decision.

The quicker you realize that theres a huge difference between current and proficient, the better off you and your students are going to be.

Taking risks on your first dual given...awesome.
