Alright Rackam has an entire episode dedicated to him, yet he doesn't seem too thrilled. Fleshing out a character we barely get to see is a nice step into the right direction, he may not have grandiose plans, or a destiny laid out for him with the chart already mapped, but he does represent the everyman he keeps the crews morale up, and keeps them humble. I'm sure they would not have made this far without his help even if it's in the background.
