This post contains spoilers for the end of Tomb Raider (2018).
Before she was a dual handgun-wielding archaeologist of supernatural artifacts, Lara Croft was a bike messenger and hobbyist MMA fighter in London. All iconoclastic, video-game-turned-movie protagonists have to come from somewhere, I guess, and the new Tomb Raider aims to spell out Croft's backstory several steps before she was ever raiding all those tombs. That means loads of exposition about the death of her father, the often disambiguated Lord Richard Croft (Dominic West), and a distinct moment, standing at the precipice of a newly opened sepulcher, where she becomes the Tomb Raider.
The best bit comes just after the end-credit title card, when we learn just exactly how she acquired her default weapons of choice: those two Heckler & Koch USP Match pistols. Of course, they originate from an unlikely place -- fitting for a reboot attempting to overwrite many of the franchise's assumptions of who Lara Croft is. This Lara Croft -- actress Alicia Vikander's version -- gets her guns from a curiously well-stocked pawn shop.
