could be realy
I think it could be one of three different things
1) She is so excited to see her Crew and worries about her ship that she blocks out everything else. Like we saw the night before.
2) Her Crew is her Family, so she can't fathom that some of them see it differently.
3) She sees it but ignores it because the truth is too hard to handle. That's what the following scene could suggest. She's fleeing into work, so she doesn't need to confront the problem.
Ether walk is not something Naomi is used to. She doesn't really know what to do, some error while excited is to be expected.
She indeed flees into work later, but it is more like polishing her saber. She has some problem, even MC could see the problem, yet she has to deal with it on her own, so she just pushes everyone else out while working out a solution quietly.
Really she couldn't have anyone telling her they have a new captain, otherwise, she either has to acknowledge the new captain, or ends up in a direct confrontation, which she would like to avoid even if she could win.
