I don't like those implications, AT ALL.
As you all have already noticed, throughout the season there are many not-so-subtle hints at what could happen to our beloved Irving. What had me fully and inevitably concerned was the 3rd shot and the title of the most recent episode: Attila.
Attila was a Hun warlord, famous for many feats (for his people, at least), majorly for conquering severe parts of Europe. Even though he himself has died from an internal bleed; his son, Dengizich had his head cut off after dying in battle with Romans. I am not entirely sure how exactly it would apply to Irv, but It's yet another thing referring to a beheading.
It is clearly not just my overthinking and all of this is intentional. I most likely might have missed or got some things wrong, so I'd love to see your discussion about all of that!
