Dimming his own lights, Zenyatta stops to place Bothi on the ground.

"If you wish to wait here, I will scout ahead to see what the source of the light is." And he'll leave Bothi with Hope too. Zenyatta doesn't want to endanger them even though they are starting to prove themselves more capable than he first thought a lullabud would be at their age. Though on a related note, Bothi may prove helpful should something come toward Hope while he is gone.

"Would that be all right?" Zenyatta is, after all, the escort on this quest.
