Oh, phew.  Earlier, I was worried Walky had just decided not to tell Joyce about her past because it was inconvenient to his desires to be superdatingbuddies with her.  Because that would be kind of petty.  But here we see he tried to tell her, but Joyce shut him down.  Because of recent developments.  Neat!  Nice writing, me!

Well, okay, ignoring how awkwardly Joyce answers Walky’s question in a way that implies the opposite of what she’s actually suggesting.  Not nice writing, me.
