I think the main thing that happens with Bruce is not necessarily that what happens to Selina changes his mind about her, because he’ll always love her.
I think it’s mainly he realizes how much Gotham has been affected by people because of him and his existence in Gotham and his position in Gotham.
I think anything, what happens to Selina in Episode 3, is a catalyst for Bruce’s decision that he makes at the end of the season.
He’s definitely going to see her in a different light and he definitely doesn’t agree with anything that she’s doing.
