This is Derek we're talking about. The villains on this show would nuke the moon to keep him from winning the lottery.

My guess is Derek and whoever Blake was in her past are together but she gets the attention of The Darach, who abducts her, fakes her death, brainwashes her - the works. The hunters use his grief to get Kate in the picture to seduce Derek and the rest is history.
