The final scene showed Captain Sandy calling bosun Ross McHarg and asking him to be her witness.She then called Alissa and said:“Yesterday, when you said, ‘Yes Sandy, I mean captain,’ that was the f**k you to my face. Your insubordination and lack of respect for this [captain] position is insurmountable.”The episode ended on this note. In the upcoming installment, Captain Sandy might ask Alissa to leave as the mid-season trailer featured a new stew onboard.In an interview with eonline, Alissa shared her opinion on Captain Sandy and how she favors the deck team over the interior crew. The stew said:“You don't say good job to one team when there's other separate departments. It's rude. She’s [Sandy] actually part of the deck team, she leads them, she gives them their plan. With the interior, she just sits down at the dinner table and says this isn't good enough.” View this post on Instagram Instagram PostShe further stated that she was shut down whenever she raised a concern to Captain Sandy. If the next episode features her firing Alissa, it won’t be the first time this season that she would be letting go of Captain Lee Rosbach’s crew members.Within a few days of Sandy’s arrival, she fired deck stew Camille Lamb. Only time will tell whether Captain Lee will support Captain Sandy’s decision of firing the interior team's members.Below Deck Season 10 airs new episodes every Monday on Bravo at 8:00 pm ET.
