Yes! ..Though El is kind of avoiding the fact he is/is supposed to be a hero, but if he learns about Kamala's experiences, he could open up. The current research is kind of a good lead-in for those sort of talks at least.

And oh man, I feel so bad about Peridot. I feel like Eleven's unwavering faith in response to her skepticism definitely didn't help her there. Infinite apologies.
