Alien: Covenant - 18 WTF Moments

4. How Does David Have Time To Impersonate Walter?

Between defeating Walter and getting on-board the Covenant, David has to do the following things: fix his voicebox, melt off his hand, take Walter's clothes and change his accent to be American.

It's pretty tough to fathom him having enough time to do all of these things, especially repairing the voicebox, which makes the film's final reveal feel not only laughably predictable but also eye-rollingly contrived. And doesn't it make Daniels seem pretty stupid, too?

Again, it's another "because it's a movie" thing, but this could've been ironed out so easily in the writing stage.
