Early next year The CW's DC Comics TV universe will grow to include Legends of Tomorrow, but this fall Arrow will enter its fourth season while The Flash will premiere its sophomore outing. In Season 2, Barry Allen a.k.a. The Flash (Grant Gustin) will face plenty of new villains, develop new lightning powers and even meet some new speedsters.
However, in addition to all the storylines and characters set to debut in season 2, The Flash will also continue to develop relationships established in Season 1. For instance, Iris West’s (Candice Patton) friendship with Barry was a throughline and, according to The Flash executive producer Andrew Kreisberg, she will become a bigger part of his superhero work in Season 2.
“Iris slides into [the role] very naturally. She’s a born leader. One of the best things in the premiere is Barry decides that he wants to work alone because he doesn’t want to risk anyone else’s lives, and Iris is really the one who gets the band back together again. She’s the only one who can stand up to Barry.”
Iris spent most of Season 1 as one of the few main characters kept in the dark about Barry's identity as The Flash and the goings-on at S.T.A.R. Labs. However, after learning of Barry's superhero activities, Iris stepped up to help the Flash fight Gorilla Grodd and, after their conversation in the Season 1 finale, the relationship between Barry and Iris seems to be mended.
Given the precedence set by Iris taking on Wells role as Barry's coach/mentor/voice of reason during 'Grodd Lives,' it makes sense that she would do the same in the Season 2 premiere with the S.T.A.R. Labs team recovering from the events of the finale. Additionally, it will give the character a new direction since it seems to be vastly different to her ongoing search and reporting of "The Red Streak" or her anger toward Barry for hiding his identity during Season 1.
That being said, The Flash established many different character relationships and dynamics at its core - such as that between Barry and Joe West (Jesse L. Martin) - and the will-they-won't-they romantic dilemma of Barry and Iris may be one of the weaker aspects of the show. Although it seemed the two had acknowledged their romantic relationship in an alternate timeline and moved past it in the season 1 finale, it will likely return in Season 2 - especially with the characters working together.
The specifics of Iris' storyline throughout Season 2 remain to be seen - if she does develop a romantic interest in Barry, how she adapts to the leadership position of Team Flash etc. - but Iris having a part in the story aside from her relationship with Barry will hopefully provide for a more compelling arc in Season 2.
The Flash returns for season 2 Tuesday, October 6th, at 8PM on The CW.
