I had much the same thought. Looking for trouble? I just don't get it.
I think it is a fair assumption the primary came onto the boat looking for drama and honed in on Kate. Kate has an admitted RBF, has had a horrible season, but remained professional. The primary was looking to upset the apple cart, likely for more camera time. While I am glad she apologized, she stopped her 90's party to do so in an abrupt manner, and I just rolled my eyes, as it was an obvious ploy for attention. She was there for her bachelorette, yet spent the majority of the time focused on Kate. Good luck to her husband, as he is going to be alpha femaled and one upped into infinity (or as long as they stay married). Not a fan of the primary what so ever.
Kate mentioned on IG this week she did not wear her epaulettes on the final charter, as it was clear the crew did not respect her seniority. She was truly a worn down dog that the primary thought would be fodder to be kicked around a little while she was down.
I thought her friends were just lovely, however, and before the ill timed penis cake, it was nice to see Captain Lee enjoy a real conversation with polite guests that were just sweethearts the entire charter. I think its telling the drama filled drunk primary was not at the table, thereby leaving room for the ladies to enjoy Captain Lee and have a great conversation. The cake may have been ill timed, but its not Kates fault the primary became drunk to the point of having to go to bed. She asked for the cake, and indeed she got what she asked for. She can hear about it later and reflect on her drunkenness as the reason she was not there for it. I will say I thought all the "hair" type of stuff around the cake was weird. I said to my hubby, why not just a nice big D with some little cake balls at the base? We don't need this level of skewed realism.
