13 Things That Would Have Happened After 2016 Movies Ended
3. Toby Kills Marcus - Hell Or High Water
Texas ranger Marcus Hamilton's (Jeff Bridges) final confrontation with bank robber Toby Howard (Chris Pine) not-so-subtly suggests Hamilton won't be letting his investigation go, and that the two may meet up in the near-future to settle their differences once and for all.
Toby being the more ruthless and obviously younger of the two men, is far more likely to come out of it on top, and considering that Hamilton is actually retired at the end of the movie, he won't be able to bring any official backup with him.
Given Toby's determination to protect his family is juxtaposed with Marcus' clear loneliness following his wife's death, the eventuality of this meeting seems pretty obvious.
