The latest details and spoilers for "The Flash" Season 4 features a new version of Harrison Wells in the show and how Barry Allen's absence affects the West family.

A new Wells for Team Flash

It seems that the executive producers of "The Flash" will continue the trend of introducing another Harrison Wells in its fourth season. Tom Cavanagh told Comic Book Resources during San Diego Comic-con that the show will start with Harry Wells until the team finds a way to bring another version of himself to Earth 1.

"And so this year, we've had a different villain and so I think there's going to be areas that we could use a different Wells," Cavanagh said.

Cavanagh has been part of the show's main cast for three seasons and has played different versions of his character. The first Harrison Wells became Barry Allen/The Flash's mentor and the founder of S.T.A.R. labs, but it turns out to be Eobard Thawne/Reverse-Flash in disguise after he killed the latter and took his place.

The second version, Harry comes from Earth 2 and helps Team Flash defeat Zoom in order to save his daughter Jesse. The third season introduced H.R. Wells from Earth 19 and provided the comic relief for the show due to its dark tone. H.R. was killed by Savitar during the season 3 finale disguising himself as Iris West to prevent her death and change the future.

While details on Cavanagh's new character are still unknown, it is interesting to see how this new Wells fits the mold in the show especially his relationship with Cisco Ramon since he has interacted with all three versions of the character.

The West family

Candice Patton shared new details about Iris West during "The Flash" Season 4 as she stated in an interview that Iris will step up as the de facto leader of the team. This also gives audiences a chance to see how the whole West family copes with the absence of Barry, as Wally West/Kid Flash tries to live up to his mentor's expectation being the only speedster in Central City.

Keiynan Lonsdale teased that both Wally and Iris will grow closer than ever in the show due to their shared tragedies and they are looking out for each other.

As for their father Joe West, Jesse L. Martin stated that his character will be proud of how his children matured in the show and will support them the best way he can.

The tone of the fourth season will return to its fun and exciting roots as Barry will have a more positive outlook on life after his time in the Speed Force and face a new threat in the form of Clifford DeVoe/The Thinker.

"The Flash" Season 4 premieres on Oct. 10 at 8 PM on the CW Network.
