WA hugged each other a lot in the S3 finale, mostly of relief. Relief that Iris was alive and well, relief that her name is back on the byline, relief that Barry was safe from Savitar because Iris killed him. They were finally able to breathe with ease. And with the season ending with Iris saying "I've always been Iris West-Allen" (That other scene with the SF didn't happen. Shh!), I can't wait for them to plan their wedding.
Anon that hug in the Time Vault was the most beautiful thing. Barry was so happy he was almost crying. He was squeezing Iris so tightly I was a little worried for her being able to breath. I mean look at this…
THEY WERE SO HAPPY
Damn this show and their need for cliffhangers :/ Why couldn’t season 4 end with them going to a wedding cake tasting or something?
