I don't know what the big rush is. Saru should give them a week off. Probably should have stayed on Earth for a spell.
Wanting answers.
Sure, everyone wants answers... but you're going to need an alert crew to find them so fix them first.
That's logical and practical and not addressing the emotional need that is presented within the story.
I don't think it is unreasonable to say that there should have been a mostly Earth-bound episode. So far, each episode has been heavily plot driven (albeit with character moments). A character-driven episode would be mostly welcome at this point, in my opinion. Furthermore, they could have done more to give a sense of what the mental health needs of the crew are. As portrayed in the last episode, the crews problems are largely ascribed to not getting enough R&R. R&R is not a panacea for mental health problems. People can still feel stress after taking rest. Indeed, it could cast Detmer's problems more starkly if she were seeing some people moving on, others not.
