 In the chapel, just after Purvis fake chestburst, there is an extended line   from Call, stating she recalibrated ground level, sending the ship into an   uninhabited quadrant of Earth, before she mentions time of impact. After   Ripley asks if shes the new a##hole model, she replies she couldnt let   humanity annihilate itself. Ripley comments that she once tried to save   people as well; she remembers a girl that had bad dreams, but she died   despite her help, and now she cant even remember her name. After DiStephano   enters to take them with him, Ripley asks Call if she dreams, which Call   does thanks to neural processors; Ripley says she dreams about the aliens   every night, and that she used to be afraid, but not anymore, since it is   always worse when she wakes up.
