This may be Mery's way of countering Aurora's unfriendly welcome, by showing her that she is not a woman that she can look down upon with her status.
Of course, Aurora was also not a woman who would act inferior. She remained leaning against the wall even as Mery showed her her watch.
"What is it?" she asked Mery.
"First I'll tell you that it doesn't matter if Jane knows your actions, so you can actually flirt with David openly. That will definitely increase the chances of your goal succeeding," Mery replied.
"What do you mean?" Aurora became more surprised even though she didn't quite understand what Mery wanted to say.
"Now we're going to talk about my purpose here." Mery didn't seem to be planning to explain about that further, she changed the topic.
