Seeing Barry scold Wally and comfort Frankie (and then look over at Iris) made me realize how much I want to see Barry as a dad (to his and Iris' children ofc). I've loved seeing him get pepalks over the past two years, and learning etc, but I'm ready to see him grow beyond that.
I also would love to see him as a father to his kids. I think he would be very emotional and invested when it comes to his children, sometimes to a fault even. I’m not sure if we’ll ever see Barry as a parent on the show, but we do have his mentoring of Wally and Jesse to look forward to so far!
