Morgana,
Thanks so very much for your comments! You, as usual, have hit the nail on the head with regards to Lois. After all these years her heart has softened and, even though she was absent during Lara's formative years, she's still proud of the woman that she gave birth to. With regards to Martha and Lois's conversation, I wish I'd thought of that! I, like you, think it would be an epic discussion. However my thoughts behind that situation was that Martha didn't want to rock the boat. Clark had agreed to the conditions and she wanted to support him. I also feel that she was so relieved that their grandchild was living at their home she wasn't going to do anything to potentially cause trouble. Though knowing Martha I suspect she thought a lot about what she'd say to Lois if they ever met.
