Obviously there was no mention of Tyrion's chain. However, did anyone notice the clanking sounds in the background during his scene with Bronn/Varys? It is very apparent at the start and somewhat noticeable towards the end. Wasn't there something in the books about the sound of the chain being made a constant noise throughout the city? Maybe it was because I was anticipating seeing or hearing discussion of the chain, but it was the first thing I thought of when I heard that noise. Is there an obvious explanation for it/does anyone else hear it?
