I don't feel sorry at all for Jill. She is just as greedy as she was when the show first debuted. She doesn't need any more money; she has more than enough to start her own business. But, that's not good enough for her. She always wants more, more, more. She's not interested in bonding with Lauren. If she were, she would have given Lauren time to adjust to the idea of them being sisters.
I understand she has wanted to find her "real" family for several years now; but, she has been way too pushy and forceful with Lauren. When Liz died, Jill didn't wait two seconds before running to Lauren demanding that she be welcomed into the Fenmore family with open arms. When that didn't work, it took another two seconds for her to demand "her half" of the Fenmore estate.
Jill is greedy, plain and simple. She doesn't have a caring, compassionate bone in her body. She's been that way since day one and I don't think she will never change. Quite frankly, I hope Michael rips Jill's claim to the Fenmore estate to shreds and that she will finally stop being all about poor little "me, me, me"!
