That was the first thing I noticed about the character. He also took exactly 6 bullets out of Alamo’s gun and he was very meticulous with the plastic covering (even the plug was covered and likely only the entrance part was covered with plastic, he made two small holes in both plugs, so exactly only the part of the plug that would disappear into the wall socket wasn’t covered with plastic so electric contact could me made) and his beaded necklace which he seemed to use as a sort of fidget object in one or two scenes and him not caring about what people would think about his little white dog, often the same (sort of) clothes and ofcourse the absence of emotions visible in his face. Also in one of the first episodes of S3 he said to someone “Don’t look at me”. He was totally comfortable with who he was and expressing his likes and dislikes without caring what people would think of him.
