A crisis emerges as the batarians accuse him of carrying poisons, and Shepard is called upon to resolve the crisis.
Shepard can either choose a diplomatic or an aggressive approach to the conversation, convincing the batarians into freeing Daniel, or signal a squad member to shoot one of the batarians, resulting in Daniel's death.
If Shepard is able to charm or intimidate them into complying, the Commander agrees to let the batarians leave unharmed. Shepard can renege on this promise leading to a scene where Shepard's team guns down the batarians. Daniel survives but is horrified by Shepard's actions. Mordin, however, agrees that killing the batarians was the correct choice and admonishes Daniel for being naive.
If Daniel survives, he sends an e-mail titled "Things are quiet again." to Commander Shepard.
