So Cadet Tilly, seemingly socially awkward, turns out to be a party animal! I found that funny, unexpected, refreshing, and it made her somewhat neurotic persona much more bearable, and her character more interestingly filled out. Also, in spite of her "flaws" - and we all have flaws - she has now substantially helped Burnham on multiple occasions in significant ways. We might have thought Burnham had it pretty much together, Vulcan logic and training and all, but Tilly is really helping her to be more complete. Tilly helped Burnham overcome her trepidation about opening the case and viewing the message Captain Georgiou left her, she helped in the shuttle rescuing Sarek, helped Burnham socially integrate and deal with her feelings, and more. Burnham, initially respectfully tolerant of her snoring cabin mate, has really made Tilly her confidant, to great purpose. I was initially somewhat repulsed by her, and I think she was designed to have that effect, though I admit I was highly judgmental. But then as her character developed, I was reminded that everyone can have profound contributions, and life experiences that are important to share by way of empowering others, and I think the writers also intended to impart that lesson. We are also reminded that people of lower rank (though for the time being, Tilly outranks no-rank Burnham) may have wisdom to impart to those of higher rank, so we should always remain receptive to ideas and reflections of others, no matter the source. So I have a new regard and appreciation for Tilly, and feel a little embarrassed by my initial limited judgmental assessment of her. I think she CAN make captain one day, presuming that she avoids some horrific sacrificial fate beforehand, and given her sense of service and dedication, that is not an impossible fate. But I hope she sticks around.
