"Wrong you were, my technician friend. Forty people, our deaths could have saved."
Sonya feels what she assumed normal people feel seeing others die, grief and horror. The destruction of the Aurora Grey brings back all of the raw emotions from the Battle of Ossus. Emotions she had denied at the time. Master Dao's words returned "Through you, your emotions must flow. As they empty, peace you find. Holding on to emotions, this is the path of the Dark Side. Denying the existence of the Dark Side, denying emotions is. Something you cannot afford to do, this is."
She lets the grief pass. The only sign of her inner distress is a single tear as she reaches the conclusion that Master Dao must be one with the Force or he would have searched for them. As calm returns, she promises herself a good workout once they enter hyperspace to burn off any chemical residue from her emotions.
