In “Kapiushon,” he finally even got that Bratva chest tattoo we’ve been looking at on his chest for the past five seasons.
We’ve seen Oliver becoming a part of the Bratva, learning Russian, and gaining many of those skills he had as the Hood back in Season 1.
Season 5 of Arrow has primarily been about bringing Oliver Queen’s journey full circle now that his five years of flashbacks are almost up, and the flashbacks have mostly been filling in a lot of blanks.
“Kapiushon” did more than just fill in blanks, however; it also made a huge change to Oliver’s backstory by revealing that his real reason for killing all the time was that he liked it, not to honor his father.
