I feel like I only got to know all of the potentials from S7 superficially. We know just a little bit about most of them really. This was one of my criticisms of S7: too many potentials were introduced, which sacrificed a deeper exploration of any of them individually (aside from other problems I had with the potentials). Of the ones we get to cursorily know, I don't have a strong favorite. I don't think I care for them much yet really. Amanda is cute and completely inoffensive, but that's the most I find I can say. That's like meeting a friend of a friend a couple of times and thinking they are a decent person. But whether we could get along in the long run, whether we have enough in common to be friends and so forth remains to be seen. So that's kind of an analogy for me. I guess I would choose Amanda as my favorite, but then again I can't really say I know her all that well, so I'm not sure that opinion I have of her is worth much in the end. Then she died.
And I haven't read the comics yet either.
I'm also the kind of guy that doesn't place much value in a relationship until its been proven and when we have shared something real. And also the kind of guy that reserves an opinion of a tv character until I feel I have some real sense of who they are.
