Fair enough but if you want Roswell to be more justified i would suggest for him to talk about not being ok with Dave inviting Tyson earlier when it was relevant.
Right now everyone talks about how they feel about Daves action then about 2 weeks later Roswell decides to finally give his opinon right after talking about very heavy stuff which already has Dave realing trying to get to grips with it.
It just looks more planned and opportunistic the way it is now. Why would Roswell wait so long after it was already brought up unless he was hoping to be able to use it later as amunition. If it was to wait till they could talk alone they've had like 2 weeks and plenty of opportunities to talk in private. If Roswell didn't care at the time to bring it up why does he care now.
