Thomas does his every-other-episode good deed and offers to help Andy read and write and says he won't tell the others. All this despite Andy avoiding him like the plague because, we learn in this episode, that Andy knows Thomas is gay and adopts some form of 1920s Restrained Estate Staff Gay Panic. To his credit, Andy apologizes for treating Thomas poorly, and Thomas lets it go. Oh, that Barrow. So complicated. Maybe he'll also teach him to hate gay people a little less, because, you know, they can help people read.
