This tiny section in the third trailer after Grace wields the wrench at Rocky is sooo important to me, because we see Rocky kind of doing the same thing back, but! He's not holding any tool or weapon or anything like Grace is, which if I recall correctly (and please correct me if I'm wrong) isn't actually ever mentioned in the book. But it is mentioned in Andy Weir's google doc on Eridians (under "limbs"):
Maybe I'm forgetting where it is in the book (entirely possible) but honestly it's giving me a lot of hope that they're going outside of strictly what is said in the book to make it more interesting and cohesive as a visual work as well!
