"we just cant meet eye to eye" while giving her sister her back.
Lillian is seen as a saint, and she herself has good intentions, but is very naive and cant see further than just "my sister prefers flaunting the riches instead of feeding the poor"
This has potential for being good, i especially loved the scene where lillian said that she didnt want to attend the wedding because "the duke will want to switch brides" like wtf, that level of confidence and then her sister ignored that and asked her to be happy, guess what, lillian couldnt meet her eyes and just felt unconfortable. Cause she knew she was sacrificing her sister.
