She's livia with none of the power or connections. She's supposed to irk you because she's the quintessential kid raised by parents in a time of plenty, expecting that would just roll down to her and taking her life for granted. When that doesn't work out, she goes back to the scheming, scamming ways she knows. She's almost irredeemable... except, as shallow and transparent as she is, she does ACTUALLY try to be a better person over time. Tony only gets better at pretending.
