Re: Some thoughts on Losing the Peace (spoilers for the book obviously
I agree with your assessment of Chen, Paris.
I'm fond of the character, and I appreciate her sense of humour quite a bit
. I also enjoyed her story arc in "Losing the Peace".
Maybe I'm in the minority here, but I actually quite like Ms. Chen. The idea of making her a surrogate daughter to Picard was a wise move on Christopher's part. With the death of Data, Picard really hasn't been anyone's mentor in a few years time. Worf is great, but he knows who he is. He's continuing his "schooling" in the ways of command through Picard, but he's not his "son" in the way that Data seemed to be (at least to me).
To me, Chen (along with Choudhury & Elfiki) seems to represent the next group of people that Picard will make into his starfleet family. He did it on the Stargazer (the Asmunds, Greyhorse, Joseph, BenZoma) and he did it on the Enterprise (TNG cast), so there's no reason to think he won't continue to operate in the same manner as he always has. I think Chen will continue to grow and eventually become as indispensible to Picard as officers like Geordi and Worf currently are. We just have to give her some time. She's only been on the ship for two TNG-R books and the Destiny trilogy.
I agree with your assessment of Chen, Paris.
