It seems like they just took every kink represented and threw it into his character. So someone says "Can Halsin please top me in bear form?!" And then they went with it. I don't mind that it is there, but in the context of his other issues, it goes from being something actually rather sweet (that he is so impacted by his feelings, not progress to sleep with a bear part), into something that is dominant in how he views and reacts to his romantic and sexual relationships.
