They grow closer and closer, executive producer Andrew Kreisberg tells EW.
He lost it for a second and hes got it back, Gustin says.
He refuses to accept the reality that she will die.
However, that doesnt mean the couple wont have concerns along the way.
Its that push and pull.
Shes accepting that this could be her potential fate.
Well see Iris deal with those thoughts and emotions as the season plays out.
Part of looking to the future, however, does not include wedding planning.
We will see that come up in episode 21, Gustin teases.
Theres more of just trying to save her life; its the more pressing matter at this point.
Still, fellow executive producer Todd Helbing notes that this journey will only make the couple stronger.
They have to figure out how to work through the biggest tragedy that could befall them in the future.
