Yeah but for me it changes the dynamics of things. In the game, Dina goes along because shes invested in Ellie. In the show, now she has additional investment because she was directly hurt by the group and was a first hand witness etc. In the game its significant because of the moment where Ellie decides to once again pursue her vengeance (after a lot has already happened) and Dina just wants them to resume their life together. Ellie cant let it go because she was there and its burned into her mind, Dina can only stretch so far to support Ellies quest for revenge.
