This scene was also interesting from the perspective of the audience because we I - on the one hand - wanted to see what will happen out of the David-Neomorph interaction and Oram's putting it to an abrupt end made me uneasy somewhat but in the end he did a good thing for his crew. For a moment he - for the first time ever in the film - was almost in absolute control and pulled himself together. Him insisting on going instead of Daniels to check up on Rosenthal was meant to be a chance for him to reinvent himself. It actually adds so much complexity to his arc (mostly through Billy's superb acting, not writing itself) that he ended up the way he did. When I was watching the film for the second time, I just couldn't stand him dying. Oram is easily in my top 5 best Alien characters in the franchise.
