Sitting in the bushes, Meltharet observes an unfamiliar woman approaching. Whether it was Mirabella or not, he couldn't know (or if it was her).

Meltharet watches the actions of the unfamiliar woman. If she enters the house, he waits five minutes and then comes out and knocks on the door. If, however, he realizes that she is Mirabella, he cautiously appears and politely calls out to her.

Of course, he only comes out of hiding if no unfamiliar person is following her.
