I can tell from the content in this thread.
You are definitely Team Edward, and very against Team Jacob.
Well let me tell you...if you ever met a Jacob in Skyrim. Or maybe you haven't even met him yet. It is possible Lydia fell in love with him and he turned her to a Werewolf. Quite common in Skyrim really...married men/women, getting bored of their lover and finding someone else. Just be glad you didn't marry that woman from Riverwood! That one elf always visits her...
Try turning her to a vampire. Us Edward fans sometimes need to force vampirism upon others...
Being very anti-Twlight, my partner will instead input. She said: "Wrong, because 1. they are not werewolves, they are shapeshifters and 2. you either are or are not a shapeshifter, you can't 'become' one".
