Are you sure about that? I don't see it on my playthrough. No option to go home with her either.

It is what it is, but I find that most of these branching character paths are exercises in frustration. Sometimes there's new content on a path, but a lot of times it just seems like the existing content has been cut in half. And when you take the first few steps you're quickly irrevocably committed to a path where there's little to no indication of the destination.
Having to choose between lab rat, whore, or domme Penny without an option for just "a loyal assistant that enjoys getting banged" is a case in point.
Tasha's paths at least have some new content, but agreeing to what seems a fairly inconsequential date with her locks you into a romance path and out of dosing her, without any warning. Had to start over there. Then picked a serum path where I'd no idea what it'd lead to. Had to start over again and pick the other branch.
I don't get Diana's old serum option to have her want to have sex any longer, just the blowjob one. But that one's been fairly redundant for a while anyway, since she's open to banging from day one.
