Not bad at all but unfortunately my least favourite of season 2 so far! It was an extremely original idea and the gang were as good as ever as their ancient ... relatives lol?! Wasn't a big fan of the monster really but the reveal was very nicely handled and actually caught me off guard! Loved how the gang couldn't care less about the culprit of their original mystery once the story is over.
The whole episode felt a bit out of place in the series, despite being an interesting change of pace! I respect the idea of the episode more than anything, just can't see myself rewatching it too soon.
