'West-Allan' wedding for season 4

Executive producer Andrew Kreisberg confirmed that Barry Allen would finally marry Iris West in the fourth season of the "The Flash." The two were engaged in season 3, and they were supposed to get married after they defeated Savitar. Unfortunately, it did not happen as Barry is forced to go to the Speed Force to save the Central City leaving his family, friends, and Iris behind.

"They are finally going to get married this season, Kreisberg told Entertainment Weekly. "Then is going to be: Can they stay married with everything that's coming up against them?"

Kreisberg hinted that just because they are married, that does not mean things are going to be easy for them afterward. With Barry Allen returning as The Flash in Central city, he will have to think of a way to balance being a superhero and a good husband to Iris.

Barry's return from the Speed Force will grant him new knowledge and abilities that are not seen in the past seasons of the show. He will likely use these new found powers to fight a new foe, Clifford DeVoe a.k.a. The Thinker. Kreisberg also teased a new and exciting change for Harrison "Harry" Wells in the first part of the show before introducing a new Wells in the second half.

No Julian Albert this season?

Cast member Danielle Panabaker revealed new details of what happened to Tom Felton's character, Julian Albert after season 3. She told Digital Spy that things did not work out between them as Caitlin Snow does not feel the same way towards Julian, as the latter felt for her.

Fans have teased a romantic relationship between the two as Julian was instrumental in helping Caitlin overcome her "Killer Frost" persona.

Julian was also revealed to be Doctor Alchemy, and he was under the influence of Savitar.

Caitlin is seen in her normal state in the SDCC 2017 trailer hinting that she will return to Team Flash. It is unknown if she still retains her Killer Frost persona or will she use her powers to help protect Central City.

The new titles for the next "Arrowverse" crossover will have the heroes face a new challenge bigger than he Dominators that invaded earth last year. Fans have speculated that the new big bad in the crossover could be Mongul and he will also bring his space station, the Warworld with him.
