There is an interaction early on and you realize “Oh, they see each other.” These two people naturally know that this person could do me harm, this person sees me. Others don’t notice or are blind to my abilities, but this person sees me. Goodsir represents something to Hickey that Hickey could never admit, even if he felt it. He could never admit that Goodsir’s ethos, his belief system, is completely contrary to Hickey’s. It’s the antithesis. And for him to admit that would destroy him. Hickey represents so much to people that they wish they could be: that anarchic, carefree, fearless person. He just acts immediately and follows his instincts. Don’t worry about ethics or good, just think practically. There’s so much humanity in Goodsir. It just oozes out of him. Hickey’s used to seeing people like that and he’s learning throughout the expedition. He makes plans for Goodsir, it’s almost like a human experiment for him. He can really see the purity of man, how real it is, how long lasting it is, and what it will take. It’s definitely my favourite relationship on the show – it becomes really interesting.
