Colin comes off first as a chill and laid back high-school student which can be shown in his regular and casual fashion, later down in the series he’s then shown to have a bit of a sneaky side to him when he asks Ruby to go on a date to the Color Block Party without mentioning he already had a girlfriend. He may be considered a bit of a flirt, then he shows people that he likes to ditch girls. Also, he's the type of a mean person when he said to "keep things chill,"
