I recall watching this episode as a kid growing up in the 60s. Rather than simply answer those asking what happens next, I think it's important that everyone knows exactly what happened that led up to the bar scene. The following is an excellent movie summary provided by Wikipedia: Al Denton was once known as the quickest draw in town, but riddled with increasing guilt over the losers in his gun duels (one of whom was a teenage boy), he became an alcoholic wreck and the laughingstock of the community. A mysterious salesman named Henry J. Fate causes Denton to inexplicably regain his expert shooting touch and once again inspire the respect and awe of the townsfolk; Denton explains to Liz, a saloon girl, that this will only cause reputation-hungry gunslingers from miles around to seek him out and, inevitably, kill him. He cleans himself up and goes sober but only, he says, so as to die with dignity. Just as Denton predicted, soon enough a challenge is delivered which Denton dare not refuse. The still-weary and not-so-sure-handed Denton practices in the desert for his suicidal duel, but he misses his targets miserably and concludes that he must skip town. As he packs his things and tries to flee under the cover of night, he strikes up a conversation with Fate, who seems to know things about Denton and offers him a way out. Fate offers him a potion guaranteed to make the drinker the fastest gun in the West for exactly ten seconds. Denton is skeptical but Fate goads him into drinking a free sample, after which Denton immediately realizes its benefits. At the appointed time, Denton faces his challenger, Pete Grant, a brash young gunfighter. Denton downs his potion only to find his opponent holding an identical empty bottle. Grant and Denton both realize that Fate tricked them, but it is too late to back out of the duel. Each man shoots the other in the hand, causing injuries which are minor but forever ruin both men's ability to pull a trigger. Denton tells his young opponent that they have both been blessed because they will never again be able to fire a gun in anger. He tells Liz that Grant is lucky because he was given this lesson early. Henry J. Fate tips his hat to Denton and rides quietly out of town.
In many movies Duryea played an almost maniacal villain (watch two James Stewart movies, Winchester 73 (the original) and Night Passage) to see this. But in this Twilight Zone episode he demonstrated his ability to portray a much more nuanced, almost sympathetic character. This was a man from the era when actors made their movies great with great acting, not over-the-top unrealistic action scenes.
He also suffered from what plagued the career of Jeffrey Hunter. They were both almost prettier than the female costars...that was said of Hunter specifically....
jessie james actually he did but never hit the big one...he was Capt. Pike in the Star Trek pilot back when...best known for his role as Jesus in King of Kings. Recommend you look at his Wikipedia page and see the opinions of him from Marilyn Monroe and Ruta Lee ...he was a very interesting man indeed....😇
