WARNING: The following contains spoilers for The Falcon and the Winter Soldier Episode 4, "The Whole World is Watching," now streaming on Disney+.

The Falcon and The Winter Soldier delivers thus far on many of its promises in the trailer. Falcon jumped from a plane, dodged missiles as he winded through canyons and he and Bucky formed a begrudging partnership in the wake of Captain America's legacy.

But there are some scenes shown in the trailers that have yet to occur in the series' first four episodes. They're small moments that are easy to miss, but fans trying to stay one step ahead of the Disney+ show should keep their eyes peeled for the inclusion of these key moments.

Zemo Returns to Sokovia

While he may not have the power of Thanos, the scheming charisma of Baron Helmut Zemo makes him every bit as exciting of a supervillain. That villainy is infused with some of the same pathos, however, as at the end of Captain America: Civil War, viewers learned of the passing of Zemo's family during the fall of Sokovia, which motivates his quest to destroy all superhumans.

In the trailers, it appears he will finally get the chance to pay his family a visit, returning to Sokovia once more on his quest. This also seems to be the same scene where Bucky drops bullets in front of Zemo's face, so a confrontation in that locale could be inevitable. The series last left off with Zemo escaping Bucky and Sam's custody, so Sokovia may well be his next stop with the heroes dead on his trail.

Practice with the Shield

Ever since his Marvel Cinematic Universe debut, fans have wondered when Sam might get his turn serving as Captain America, as he did in the comics. While the trailer seemed to promise it was coming, Falcon and Winter Soldier continues to tease audiences. In a memorable scene, Sam and Bucky practice throwing the star-spangled shield around, with Sam pulling it from a tree trunk at one point.

At this point, it's hard to say which of the two heroes could take up the legacy. Given their contentious banter, there's no doubt that watching them argue over it as they compete at throwing the shield effectively could be one of the show's best scenes.

Bucky Gives Sam a Pep Talk

Not all of the two characters' dialogue is barbed repartee, and they do seem to share a deep respect for one another. Falcon and Winter Soldier  has already contained a few scenes of the two sharing their wisdom with each other, and there will be at least one more such interaction in the future. More importantly, it sounds like Bucky could be encouraging Sam to become the new Captain America.

From appearances, it seems the scene will occur on the fishing boat owned by the Wilson family, meaning New Orleans could be a likely site for the series' events. Watching Sam's down-to-earth upbringings collide with the world of his superheroics will doubtless be a pleasure to watch, and it may even restore some normalcy to Bucky's fraught life.

The Flag Smashers Ride Again

Thus far, the Flag Smashers have made for engaging villains in Falcon and Winter Soldier as their anarchistic goals clash with the order the series' titular heroes try to maintain. But morality has not been so black and white, and when Sam and the Flag Smashers' leader, Karli Morgenthau, shared an emotional moment, it was clear they were far from finished with each other.

The trailers promise Karli will mask up at least one more time, but she may not have many more such instances left. With John Walker fueled by Super Soldier Serum and more determined than ever to hunt her down, the rebellious leader will need all the help she can get in evading him. Even so, she doesn't look too worried about it.
