From what I understand their curse affects all the generations of Travelers. That being said why aren't Bonnie, Katherine, Elena, and Stefan not doomed to be wandering the earth? I mean Silas and Qetsiyah were Travellers if all the travellers descendants are cursed why isn't the Bennet and Salvatore line?
For that matter could Amara have been a sort of untriggered witch/traveller and Qetsiyah just had too big of a stick up her ass to notice? I mean Qetsiyah seemed like the type that looked down on others and was too arrogant too notice any untriggered or untrained witch's abilities. That is the only explanation for how Amara could have been part of the travelers like Katherine I bet she didn't learn traveller/tradition magic but still could use it. In which case Amara could of gotten in to the other side on a technicality.
Either way you dice it this Traveller curse upon closer inspection has really caused a lot of continuity problems. I mean even if you don't learn how to use magic you are technically a witch and by all reason no matter how distant the the blood line you would still be a traveller. So why isn't the Bennette or the Salvatore line cursed?
