So, question. Why was the title of last night’s episode called “Oathbreaker”?
Who broke an oath?
John said his watch has ended. He executed those who killed him, and now he’s handed off his responsibilities and indicated he’s leaving the Night’s Watch.
And technically, Daenerys also broke an oath and faced punishment for not coming to the home of the Khal widows after Drogo’s death, hence the impending punishment debate.
“Who broke an oath?’
Almost all of them in one form or another.
D. Stormborn was revealed to not have gone to the khaleesi “widows’ rest home” as she was supposed to do.
Four members of the Night’s Watch were hanged for violating their oaths.
Jon Snow walked away from his oath (technically he fulfilled it and then was killed. . . and then raised from the dead).
Umber is violating his oath to the Starks by turning in Rickon to Ramsey (but that might be a ruse; I doubt it though; the wolf’s head makes me think he’s not planning a ruse).
Ramsey and Karstark and Umber all had a conversation shot through with an underlying idea of oathbreaking.
The Harpy woman betrayed the Sons of the Harpy.
Arya advanced in the Faceless Men cult but is still lying about her goals.
And on and on.
Jon Snow... he's abandoning the Night's Watch.
But, whether that makes him an oathbreaker or not is open to discussion. He swore to stay with the Watch until death, but he died. The question is, "does he have to re-up?"
I have not seen this particular episode yet; so, I am commenting in a general sense.
I have found in previous episodes that within the episode there will be several examples of the title. Each of the characters shown will have exhibited what the title suggests. So, perhaps, not just one Oathbreaker; but, oathbreaking is the underlying theme.
Who broke an oath?
“your father was a Cu#% I watched him swear an oath and bend the knee to Rob Stark then he stabbed him in the heart.”
