Natasha's conversation with Fury was relatively short and to the point, though she tried to argue. By the time it was over, though, and she knew what was going on, she agreed to come back with Loki, though she warned that she'd be bringing someone else as well.
When she was done, Natasha turned, then blinked when she saw Loki standing there. Holding the headset out to him, she spoke calmly. "He wants me to come back with you. But I'm not leaving until the morning." Then she moved past him and into the house, door open in invitation.
