10 MCU Loose Ends That Drive Fans Crazy

There are tons of huge MCU moments that happened offscreen, but this one is arguably the most intriguing of the lot.

When Cap is sent back in time to return the Infinity Stones to their correct places in history, his entire adventure takes place offscreen. While we know the outcome of this adventure - he was obviously successful - many fans consider this a loose end because it just isn't as straightforward as the movie seems to think it is.

It took a full team of Avengers to retrieve the Stones, so how is Cap supposed to put them back all by himself? Sure, some will be easier than others (like the Time Stone, which just needs to be handed to the Ancient One) but doesn't the Reality Stone need to be put back inside Jane Foster? And how exactly do you "put back" the Soul Stone? It's not like placing an item on a store shelf after deciding you don't want it.

And that's not to mention the potential drama that unfolded when Cap came face-to-face with his old nemesis, Red Skull, on Vormir. How did that play out?

Again, we know the ultimate outcome here, but there are so many smaller situations that the movie leaves open to interpretation. Cap's Infinity Stones odyssey would make a cool live-action or even animated series one day, but for now, all fans can do is wonder how exactly it went down.
