It has its problems, but just a lot happens in a short span of time and a lot of things depend on other things. The vault opening kills Thanatos. So Thanatos cannot just go offline later if we want any sort of view inside of the vault; which if we don't do that then we'll have people always wanting to have seen what's inside in the events of the game properly. At the hospital, Roswell still hasn't decided if he's taking the medicine because he hasn't spoken with Oswin properly as far as the risks. If we move that conversation forward then him grieving Thanatos and the loss of his friend and confusion about what's happening alongside Dave telling him he needs to seek help is all lessened to have a monologue or side comment about him making another choice. The point was that Roswell was not in control anymore, the choices aren't his to make in the game anymore, he needs to let go.
