Fans will notice a very different tone to tonight’s episode as it centres almost wholly on Dove’s brother Nathaniel, sequestered in a remote cottage so Reid can’t find him (and to stop Nathaniel from biting bits out of people).

But when he finds it too remote, will his hunt for company have a bloody ending? You may find the action drags a little – despite Jonas Armstrong (as Nathaniel) ably taking the lead in this episode.
