well, I think they can. (tolkien would definitely disagree with me tho)
what Prof T says is: Dwarves fall in love once, and if it isn’t reciprocated they devote their lives to their crafts.
What Prof T doesn’t say: Whether they fall in love with one person at a time. Fall in love once – okay, gotcha – but nothing says that love must be for one individual alone. 🙂
