[X] Plan Shortlist -[X] Add a flashback scene with Nathan and Elena, showing their love for each other. It's hard to make the audience relate to a character only mentioned in the movie, after all. -[X] Drop hints that magic is once again on the rise, after a long period of time -[X] Add mentions of Captain America, both in the background, and potentially mentioned in the movie. -[X] Pietro Maximoff, The Scarlet Witch's own brother could get at least a few mentions in the movie. -[X] Maybe you can have Sablinova's Mercenaries be a few other named characters, who haven't been seen in the SCU so far, and probably wouldn't appear in it. (Who? And remember, all who are chosen will be killed off by The Scarlet Witch) --[X] Banjo, in the comics he's a hillbilly with super strength... maybe you can make him into a lovable southern mercenary? --[X] Thumper, a French woman with a chip on her shoulder, she's an excellent hand-to-hand combatant... sadly, that didn't come in handy, when she went against The Scarlet Witch. --[X] The Wall, also known as Joshua Waldemeyer, is a massive mercenary, exemplifying his name of 'The Wall', by his sheer size and musculature. He's a fairly angry man, but decent enough to Nathan and his crew. --[X] Don Thomas' Blue Streak, an utterly forgettable Captain America villain in the comics... you don't see a use for him in the SCU, so why not have him killed off by The Scarlet Witch? -[X] Chloe Frazer, a fellow treasure hunter. She could have been hired alongside Nathan Drake, and would make for a good foil to him in the movie. -[X] Georges Batroc, in the comics known as Batroc the Leaper could be a mercenary working under Sablinova, who she doesn't send with Nathan Drake, instead keeping him with her as a bodyguard. -[X] Doctor Faustus could be Nathan Drake's own psychiatrist, who he speaks to about his adventure at the end of the movie. -[X] Harry Dresden could appear within the movie, as just a small cameo.
