Alex who was unaware of the rage within the maid, felt like he should send a message to Rachel and Eva, since the two didn't know that they went to the arcade. He wanted to inform Rachel since she was part of the club, but it also felt like Eva was a part as well. It would be better to keep them posted as to what was happening, while the two were away.
Alex was going to send them different messages, but in the end he decided to simply forward the message he sent to the maid.

Rachel was in the middle of dodging her father's attacks, which was getting even more difficult to do. This supposed family trip, turned out to be family training instead. Of course in the first day of their supposed family vacation they did have some family fun, playing at the beach. Going to an amusement park, and other such things, but on the second day the whole family except for Rachel decided to head to the mountains.
