'Avengers 4': Is Quicksilver Back?

The Marvel fans are still healing their wounds after the catastrophic events of Avengers: Infinity War.
The Deaths toll exceeded all expectations, but now Infinity War and the Russo Brothers left us big questions about what might happend in Avengers 4. The first reports of the Marvel sets in Atlanta were already in Thor, Captain America, Iron Man and Ant Man in scenes that could be about Time Travel, B.A.R.F. Technology or the Quantum Realm, Stark and Pym Technology united (Probably) might play an important role in the film.



Also these are good news for the fans of the dead character 'Quicksilver' after the British actor Aron Taylor-Johnson who played the character in Avengers: Age of Ultron, was "Discovered" on set.

Avengers: Infinity War ends with the dead and disappearance of the half of the universe, including Nick Fury, Maria Hill, Star Lord, Drax, Groot, Bucky, Falcon, Black Panther, and the saddest one, Spiderman.

According to the Infinity War and Avengers 4 writers Christopher Markus and Stephen McFeely "Avengers 4 will not fix the events of Infinity War" 
But some of these "Dead Characters" has signed for more movies, for example Tom Holland, that has 6 movies in his contract and he's just in 3 Marvel movies and 3 on the way.
Others are Black Panther and Doctor Strange that have sequels confirmed. 
Before 'Avengers 4' Marvel Studios will release two movies, "Ant Man and the Wasp" and "Captain Marvel", we are hoping that these movies will exlore important topics for this movie like the Quantum Realm and Time Travels.
This could explain why Aron Taylor-Johnson was apparentley seen filming Avengers 4 at the same time as the leaked pics of Loki, charater that died in Infinity War.

Scarlet Witch's brother was killed during the Battle of Sokovia in Avengers: Age of Ultron, so how can he be back? The official Spanish Marvel Spoiler Fan Site is announcing  Quicksilver sightings. The article says:

"More witnesses of shooting in Atlanta said that they saw to Taylor-Johnson in the Set of Avengers 4"

Reports also say that Crossbones star Frank Grillo was in the Set in Atlanta with the cast.

Others comments circulating are about Chris Hemsworth aka Thor, using his long hair, which means he could be in the Time Travel Journey.



'Captain Marvel' is going to have the Skrulls, so we can't be surprised if these characters / villains appears in Avengers 4.
