In two separate episodes of Ozark (2017), Jonah asks Tuck to buy him a rifle. The first time, we just see Tuck buying the rifle and the clerk reveals that Tuck had checked the, "I am purchasing on behalf of someone else" box. After his purchase, Tuck gives the rifle to Jonah.
Then, we see Jonah asking Tuck to buy him another rifle while Jonah and Tuck are tying up the boats (during the scene when Garcia is delivering the $50 million). When Russ is purchasing his kidnapping supplies, we see Tuck checking out in the background.
Why? What happened to the other rifle? Or was this a singular incident and it was revealed in a "Breaking Bad" kind of way where we see a glimpse of the future.
