I think I cry the most about westallen when I think about the fact that they went from this:
Two kids. Best friends who have each other’s back. Iris believing in Barry the moment he told her that his father didn’t kill his mother, and it’s like Barry knew when he told her that she would believe him. That time when she lied to Joe about Barry taking a shower when he really went to go visit Henry.
Two adults. Who love each other so immensely - ready to literally take that next step in their life with each other.
Each time, they are closer - gravitating toward each other. In this moment, they were something more to each other. Both on the same page in terms of their feelings. And even when Barry said “I don’t know what we have here,” “but I do know that you’re everything to me..” he still knew that Iris was the one constant in his life. With all the uncertainty around them, metas continuously terrorizing the city
(or backstabbing mentors) all lives are uncertain. But the thing that’s most certain (I cannot stress this enough, y'all) is how certain their love is for one another. So damn certain and sure that it defies all tragedy around them.
Their love story is tragic, in a way. Both have been through life-altering situations. Barry losing his mother, only to lose his father right after. Constantly being doubtful of himself because people wouldn’t believe him (except Iris, of course). Barry getting relatively close to his mentors, who turned out to backstage him. Iris losing her fiancee, literally dying in her arms. Soon after, she she founds that her mother isn’t really dead, but abandoned her. Her life was a lie in terms of her mother. Not only that, but finding out she has a brother in the process. Then bam, her mother dies, leaving her wondering (in my mind) what it would’ve been like to have Francine there. Let’s just say both have been through some shit.
But they have each other - each other’s constants, each other’s certainty. Again, Barry could die any moment by being The Flash. Iris could lose her life trying to fight for justice. Everything is uncertain. But their love? That’s simply indubitable, unquestionable, undeniable, sure…. definite.
