That's fair! She checked them already and everything should in fact be all ready to go, but she supports and is not insulted by him wanting to verify that.
The trip to Jeneora... is also not notable.
Nai/Knives will find that the plant factory is all tidily set up for them in advance, ready to go. There are, approximately, several dozen safety measures in place to prevent anything from going wrong ever, especially if some but not all of the plants are removed, especially if a new and unrecognized item is added to the library, and most especially to prevent anyone from sneaking in here and messing with the goddamned controls and inputting something that is not allowed. There is a short list of what is allowed. Nai has the password and DNA-hashed signature to change it, as do Yvette and Zash, but no one else does. If nothing is inputted in the next hundred years, the plants would be free to run through this, and only this, short list of allowed items until this (very generous) safety threshold is met, and the whole thing gets shut off for safety. Presumably, if all members on the list of administrators are still indisposed, the plants can then focus on healing each other until they are safely within operating parameters again.
Yvette was very thorough in being sure that the stupid computer cannot fuck anything up, and no one that is not a member of their trio can touch anything. Is this a bit much? Maybe, but damn it, they really really need to not fuck this up, okay.
