Lope is hardly Robinson Crusoe here. Apart from David and Walter, Oram is the most interesting character in Covenant. Possibly the only interesting character. Which isn't great for Daniels.
The gay angle was dialled all the way down, and he didn't get to mourn Hallet. But Oram barely got to mourn Karine too, and T was cracking jokes after they got back to the ship despite his wife being dead. They had couples in the film, but often carry on as if the dead were barely just people they met once. If they had space to react a bit more to the deaths, it may have developed the characters a bit more. How Daniels copes with Jacob's death is all we know, because we never saw what she was like before.
