One character had several seasons to explore concepts like loyalty to the wrong people, warcrimes, PTSD, regrets. Made the character deep and interesting.

The other character had a handful of episodes to explore prejudice, and stubborn preconceptions, which made the character interesting… But the conflict was essentially resolved after and she only was around for one season.

I sometimes forget Dr Pelauski is even a thing, and then I watch a season two episode and I’m like “oh right!”
