Loyalty

I think loyalty plays a part in this play in the sense that Tichard has none. Richard goes against anyone he seems is in his way of the throne. He'll kill anyone who is trying to go against him or potentially trying to hurt him. I also believe Anne was very in loyal to her dead husband Edward. She becomes fascinated with Richard who had killed her husband. Richard also is extremely manipulative which is why he gets what he wants because people fall for his lies. In the end he only cares about himself  and won't ever give anything in return to anyone. Using loyalty differently, Edwards sister was extremely loyal to her family and odd everything to protect them. She didn't fall into Richards traps, atleast at first..
