I appreciate that Echo leaving wasn't just discarded and forgotten. The group appears a little tense after Echo's departure and it is interesting to see the effect Omega dealing with Echo leaving has on the members of the bad batch.
I enjoyed the screen time Tech got and not just the technical, analytical stuff but also a bit of emotional development. Omega is the heart of the group and I think that because of her, the rest of the squad, especially Tech are able to grow emotionally and realize that they don't have to be these soldiers anymore that have to bury their feelings. With Omega they are able to embrace the family they have.
But Omega also learns from Tech to respect the choices of others, whether they choose to leave or process their feelings differently.
The dynamics between Omega and the rest of the squad are hugely different. Everyone of them have a different influence on Omega and given her empathy, it only makes sense that she would clash with Tech's more analytical approach. But at the end of the day Tech shows her that her feelings and how she processes them is just as valid as his process.
I also liked the way Tech has so much trust in his squad that no matter what situation they are in, he is confident that they will come out on the other side of it.
Overall, this was a character episode with a little less action and a bit more focus on Tech. And I enjoyed it a lot.
