Gilga, just to make sure, Rachel has to text her husband that she is leaving while she is still in the washroom with Mel, and then give Mel her commlink. If anyone is monitoring it, it wouldn't add up that Mel, disguised as the wife, is running around the hotel while the wife's commlink is going a different direction. Rachel will have to leave the restroom looking like someone else, but not have anything that could give her real ID to anyone. Mel will give her her burner SIN so that she doesn't appear a SINless at first glance.
