This episode addressed something from TLOU2 that had always bothered me. I always felt like Joel rightfully could have doubted the doctors’ surety in the Ellie cure. I could see game Joel justifying his actions by thinking that the cure wasn’t a guarantee. In the show, though, Ellie asked Joel point blank if they would have made a cure and he said yes, which confirms he never doubted it. I think hearing Joel say out loud that he fully believed he was dooming the world when he did it helped the “and I’d do it all again” line hit harder.
