Britt Lower has talked about how Helly takes back her agency this episode, and her taking off her shoes is symbolic of that; her no longer walking in Helena's shoes.
It's funny how Helena Eagan and Mark Scout have chemistry when are in 'opposition'. It makes sense why Mark and Helly work, and gives us insight on how you would have chemistry with the same person despite losing your memories.
It's also interesting that she's more awkward than Helly, like being raised in a cult probably socially stunts you more than losing your entire personal memories. She did get pretty far with her awkward pathetic rizz, i'll give her that.
She also says she's "like the head of the company", except she really isn't, and has no real power as of yet.
Also, a great bit of acting by Adam Scott, when he laughs at Helena's banter, he starts a confused look on his face, almost like Mark is wondering WHY he has chemistry with this woman he met just a minute ago.
