Three Layers of Iris Dealing with Barry's Disappearance
1. A “hardened” Iris that challenges Cisco on whether Barry is still alive and insists they should move forward. This is Iris putting aside her feelings for the sake of the city’s wellbeing.
2. A more vulnerable Iris with Joe, who admits she can’t sleep in their bed without Barry, who doesn’t like the idea of grieving Barry as dead and holding a funeral for him.
3. The real Iris who confesses she’s been trying to keep running like Barry wanted her to but quietly cries when she’s alone for him to come back to her.
