Donaldson

Although appearing in the novel, he is not given a name until he is shown in the movie and thus I'm only going to be talking about his movie counterpart. Donaldson is an Arrowhead soldier who had traveled to the store with two other soldiers, these being Morales and Jessup. He is about to leave with supplies when an military police officer informs him and the other soldiers they must come back to the Arrowhead base, but is soon unable as the mist swallows the store up with Donaldson inside. He is only seen briefly afterwards except when discussing the situation with the other soldiers and when disapproving Jessup's decision to leave. He comes back into frame when David's group forces Jessup to search for Donaldson and Morales, wherein the group finds him, along with Morales, hanged as a means of suicide.
