I will say this, with Halsin's personality it isn't required that he has the tadpole at all. It totally works that he is just there because he wants to help.
The issue is that in act 3 they don't really focus enough on it - friendship or romance - that he feels an obligation to help his friend or lover. He says so, but it seems more like a sidenote of "dang, I promised".
And with how his libido suddenly goes absolutely crazy, it seems like just a way to get into people's pants. So, one more point for toxic nice guy behaviour.
Had act 3 been implemented properly, then this wouldn't have been much of the issue. But instead of focusing on that,nthey threw energy into you being able to screw a bear and a very forced romantic attraction to everything.
