The mom is very aggressive and I find it kind of hot!
There seems to be a spectrum from the mom to Celia. The sisters are in between, but Sara seems more eager and Caroline is slow to come around and when she does, there are boundaries. Lily and Macy will probably fall in there somewhere. Lily seems kind of eager and a partner in moving Sara along. Macy may wind up being a girlfriend. I think the therapist is managing some corruption of MC with her BS Freudian stuff and may be the grand master behind it all. Olivia and the Aunt.....remains to be seen, obviously.
