Halsin has those spells normally in his spellbook in my playthrough. He has the brown bear shape on the left side.
Everything else is messed up about him though. The creepy way, he comes at you when you never encouraged him has to be changed.
I can say much about the romance since he is mostly in camp and I'm not doing the romance. But he is very barebone imo. So far, he doesn't really has anything going for him in act 3. I mostly use Jaheira, since her story is much more involved ( plus it's Jaheira and she is so well done).
There should be a reason, he stays at the group in act 3 , so far my reaction to him telling me, how well the grove was, was basically 'Soo, when do you plan to go back and do your duty as first druid?:
