Elijah is Andrew’s companion at the WHITEOUT, Elijah was there longer than Andrew, so he has more experience in there. Because of all those years being alone, he has grown to be emotionally deaf, generally being terrible at confrontation and can’t seem to say “No”. Although, compared to the two; Elijah seems to be the more mature and level headed in general.
And yet He can’t seem to say no at Andrew’s antics, even if it harms the both of them.
