OMG
I just realise
(BIG SPOILERS ALERT)
It's like a circle
Sam (kill) his buddy in the mines
Sydney father(kill) Sam
Sydney (kill) his father
Chase (kill) Sydney
but any of them have kill on purpose, it's like they story have been already writte.
i don't know why but i got a feeling than Chase will be (kill) by Janice's nephew in Archer cause Janice was there when Sam was killed and Janice's ancestor was William.
this will make a true circle...
but i only suppose 😅
