This is him with anybody outside of his friends and adoptive family/when he is angry (he looks the same with when he isn't angry just without the eye brows furrowed.)
And then him with his friends and adoptive family.
Notice the contrast?
Goes from very cold, to warm and at times a goof/joker (he isn't always a jokester. When he isn't joking -like how he is above rn- his eyes are just simply more warm. His eyes are cold when not with his friends and adoptive family.)
