Starfleet.
You are operating without oversight from any of the senior crew on board this vessel which is still the federations flagship. The captain and I need answers and a full briefing from you. The effect of your research had disastrous effects on the travelers. A simple apology is not enough.
If your research has the potential to have an effect on the travelers than they deserve to be briefed on it and since the are on board this ship the captain deserves to have veto power. Their lives and wellbeing are just as important as any crew members.
