iris west and that thing she does where she loops her arm with barry’s.
i bet it started when they were kids. i bet after he moved in and they had to walk to the bus together iris witnessed how some kids would push barry or pull his backpack off and throw it in the middle of the road, and so to combat that, to protect him, she started looping her arm in his. cause she was a cop’s daughter and all the kids knew that about her, and even though that didn’t keep them from saying nasty things it did keep them from touching him.
i bet that’s how it happened.
