Last weekend's San Diego Comic-Con created a buzz that Agent Peggy Carter might be seen again on the big screen soon. Get to know if this means that she will be appearing in "Avengers: Infinity War."

Per Comicbook, Marvel Studios recently shared footage of "Avengers: Infinity War" at comic-con, after showing a montage of Marvel Cinematic Universe's (MCU) Infinity Gems. A voiceover from Doctor Strange was heard before the video of Steve Rogers and Peggy Carter in "Captain America: The Winter Soldier," before Carter changed into her younger self

Will Agent Carter be back soon?

Although none of the shown footage was new to fans, Carter transforming into a youthful version of herself has many wondering if "Avengers: Infinity War" will bring about her comeback.

It can be recalled that the SHIELD founder died in "Captain America: Civil War" - something which terribly devastated Rogers.

Having Carter back could be something good for the Captain, right? But how happy of a reunion would that be if Thanos arranges it? The plot thickens.

What else to expect from this Avengers movie

In this offering from Marvel, Thanos is expected to have power over most, if not all of the Infinity Gems. Now, if the Mad Titan gets hold of the Time and or the Soul Gem, the villain could easily create havoc - to bring back the Avengers' loved ones only to kill them.

It wouldn't be something to look forward to if Carter's appearance would be for the sole purpose of her being slain.

In spite of the fact, that its common knowledge for any fan that there could be several other ways for Thanos to torment the Avengers.

Comic book added that Carter's arc in the MCU was finally concluded, even if it was through her death. As of now, it would be safe for fans to assume that the teaser shared at comic-con was just to call attention to the Time Stone, a gem that is capable of doing unbelievable things - well, that's why it should be used wisely, right?
