As a non-native speaker, I would assume that the english speaking Alien makes grammar mistakes.
In German its possible to put the words in almost every order you'd like to have. It may result in sounding a bit complicated, but it would remain right.
So you could say: The dog bites the postman.
but also: The postman bites the dog
without actually changing the fact that it were the dog's teeth in the postman's leg.
Another great source for mistakes are *false friends*.
The german word "Gift" means "poison" in English
"bekommen" means "to get", not "to become"
