Mack left the mansion the next morning to a salon or local barber shop, he needed to be in order and visit his family before anything else. Kate knew she had to visit the mental asylum to confirm that her family were actually missing. This isn't a good sign and she knew they needed to come up with something real quick.
Mack was right, if they ever find Grace or the general, she would have to give the doctor a go ahead on killing them completely. She had no idea why she had waited this long for this. She should have done it from the on start.
Nari knew she needed to go with Kate to look supportive, plus, she couldn't afford getting seen by anyone in the public yet. She made her debut last night at Beth's party, and even if her management company were already on her neck about her returning, she couldn't return now. They had no money, and had to live their fake life before the public again.
