The continued hubris by Ryan, and sometimes Blake, is a potential danger to Mikos...
...particularly as Ryan hasn't Blake's years of experience dealing with protocol and royalty, nor does he seem to recall his military training, self control, and discipline. I disliked Ryan's belligerence and petulance, which Mikos blamed on hormonal reactions; however, Ryan was a colonel with at least a decade of military experience in combat leadership, and ought to still have had his military training kick in despite the hormonal imbalance.
Then the posturing over the challenge was featured into a huge deal. Ryan and Mikos were newly mated as well as new parents. For an experienced military combat commander who probably faced making quick decisions, choices, and analysis for the best outcome, Ryan displayed poor tact, judgment, and zero respect for his mate's feelings, position, and culture when he insisted on immediate changes to rules or policies for humans. Realistically, Mikos wouldn't have been able to allow Ryan the extreme magnitude and waiving of Tygerian protocol for deliberately humiliating Mikos in the challenge. He at least ought to have kept it straightforward and fair without deceit. The maneuvering Ryan used against Mikos was not, in any shape or form, impersonal or honorable. Instead, Ryan preyed on Mikos' devotion to him as well as a Tygerian's inability to deliberately harm his nobyo to win -- he flat out cheated. Given Tygerian culture and their stance on honor and proper behavior expected toward any royal, he shouldn't have been allowed the win using that level of trickery. Although the Tygerian public get to see a different, more empathetic Mikos, that change in perception and knowledge could hurt the way the family is viewed by their people, other races/cultures, and their enemies.
I dislike cultural oppression, but I also abhor newcomers belittling a way of life, rules, establishment, protocol, and/or society, which is what Ryan did, to a degree. Even with the hormone injections interfering with his moods and attitude, Ryan's military training shouldn't have let him ever that far off course in his manners and professionalism. Realizing the drama was necessary for the plotline, Kevin behaving out of whack would've been more believable since he was younger with less exposure and training. I refuse to believe men possess the chemistry to be that bipolar once hormones are introduced to their system. I would find it difficult to believe that even a woman with Ryan's background and experience could demonstrate such extreme behaviors - the reactions, discipline, routines, would all become so ingrained and natural, they would kick in and prevent them from being rude, or to lose control to the extent Ryan did. That bothered me.
