  • The name of the episode means durability/endurance in Russian.
  • This is the first episode of the series to not feature Joseph David-Jones (Connor Hawke) after being promoted to a series regular.
  • Like the previous episodes of the season, this episode has also many references and callbacks to previous seasons, mainly from the flashbacks in Season 5.
    • The name of the episode is likely a callback to "Crucible", in which one of Anatoly's first words to Oliver was "prochnost". Anatoly and Oliver also talk about Anatoly's first lesson to Oliver, which was "living is not for the weak", that also happened in Crucible.
    • John meeting Roy is almost the exact same as Thea's meeting with Roy in "This Is Your Sword".
    • When Anatoly and Oliver first meet, he jokes about not punching him, which he did upon first meeting him in "Bratva".
    • Oliver first fighting a man bigger than his size, ending tied-up in a chair and getting interrogated by Bratva is very similar to what happened in "Legacy". When Oliver and Mia talk about getting out of the chair by dislocating thumbs, Oliver quotes Anatoly from the same episode, saying "it's a useful technique, if getting tied-up in chairs will become habit".
    • Mia having to fight four Bratva thugs and ring the bell is same Oliver had to do in "The Recruits".
    • Kapiushion is the nickname Bratva gave Oliver, originally in it was Kapot, but was changed, due to latter meaning "car hood".
    • Anatoly says that both him and Oliver have matching tattoos, with Oliver replying not anymore, referencing the events of both flashbacks and present day of "Kapiushon".
    • William says he met Mia in a fight club, referencing the events of flash-forwards in "Unmasked".
  • The press originally had Connor Hawke in the description instead of Diggle, the former who doesn't appear at all in this episode.
  • Mia tells Oliver that she doesn't cook much, to which Oliver quips that it makes sense, referencing that Mia may have inherited Felicity's bad cooking skills.
  • The green robe that Oliver was wearing before he and Mia participate in the fight club is very foreshadowing to him becoming the Spectre in the episode "Crisis on Infinite Earths: Part Four" where he wore a similar green robe after the Spectre possessed him.
