Agree, that part made no sense! If only the first born can be a Were, it wouldn’t matter if they swapped partners because the man/woman each could only have one. Trying to backtrack that made it unnecessarily confusing.

The books also made me appreciate the show so much more. I love how they fleshed out Jason’s personality and others that were just glossed over in the books, and Jess’s addition. I also understand why the show kind of went off the rails near the end, because the books did too lol.
