Diana's attention is shifted from the hologram map to Shepard herself. The longer her description goes on, the wider her eyes get. She tries to imagine such a creature, such a monster, but it seems too vast and cruel to even picture. She exhales slowly, trying to separate herself from the horror she feels after listening to Shepard's explanation.

"What kind of purpose is that?" She asks it rhetorically, though she still tries to think of any reason at all for such an act. She can't come up with a single thing.

Diana reaches out, intending to place her hand on the other woman's shoulder, but stops just short of doing so. Her hand hovers there instead, a comfort she'd give if not for the potentially disastrous results caused by physical touch right now. "I am sorry that your people are under attack by such creatures." And it isn't just her people--it's everyone in the galaxy. "If there is any way I might help you, I will." It isn't as if there's much she can do from here, but the offer is sincere.
