Gwen - Gwen asks Holiday 'What are the results of the oil sample?' so she can locate the pipe she's looking for.
Mihail - Analyzing the Grass.
Yev - Also asking Holiday about the oil, same purpose as Gwen, but referencing color. (She and Gwen will end up in the sub-levels together)
Yingxue - Double checking the cow genetics, then looking into the physical grass sample genetically as well.
Arthur - Looking at the Harvester (Two Holiday quips about the intercom interference). He replaces a faulty diagnostic part and remarks upon an odd oil stain left by the machine. GM Note; the machine may have something else faulty with it, I will detail this in my response.
Kaplan - an exceedingly intense on-sight study of the grass itself.
Isaac - Awaiting his long-desired space walk litter event. This will come to fruition shortly.
Cross/Rossi are at the moment unmentioned, which is fine, take y'all's time folks.
This is what I've noted for myself upon a brief reread, I'll get something out this coming weekend. Let me know if there's anything more specific or additional that I need to address. The next few posts from me are going to be shorter and more direct, I'm back-burnering my big giant writing nonsense for a bit to give myself time to prep for a few other hobby projects that are starting in the near future at my real-life tables, but once those are up and moving it'll be back to writing up the 'part twos'
