I think Lenny has a bit of a crush on Marilyn.
Re the girlfriend. Patty did some research and found out that she has 2 children from a previous relationship (which her son knows about) but also that the father has full custody and that for some undisclosed reason she had been judged an 'unfit mother'.
Son obviously doesn't know about that because when Patty threatened to tell him whilst bribing GF, she looked quite scared.
She then had a conversation with Michael asking him he was sure about her and the baby etc and he said yes.
Nothing since.
Ellen's replacement is not working with Lenny. He uses a private detective who looks a bit like her, maybe that's who your DH was thinking of?
I agree the 'relationship' is the law firm (doh) but how is it going to happen so quickly if there are only 2 eps left?
Agree on Frobisher being set up, but quite frankly I'm not that interested in him when there are so many loose ties in the original storyline!
And also what is the point of the whole adoption/sister's a cow/dad's a bully thing?
Is it to show that Ellen's slowly seeing Patty as a mother figure to substitute her shitty family and that she is going to flip now that Patty's disowned her?
I like the little conversation she had with Dead David. They had a really cute relationship in the first season.
