I had totally forgotten about Elliot's realizations about his sexuality and gender. That's weird, considering I so seldom (read: otherwise never) see characters who are agender like me, at least not in any way that is ever established. (Well, these days I say "nongender," i.e. no gender identity, because I've gotten sick of the fact that "agender" refers to both a gender identity and a lack of a gender identity, and the two aren't actually even similar.) Then again, there's plenty of characters that we don't really know to be male or female, where we're just assuming.
(On a side note of being a nerd nobody asked for, "inflammable" originates as "inflame-able," i.e. "able to be inflamed." Then language evolved and people started dropping the "in" sometimes, because it sounds like a negative prefix, and now use of "inflammable" is discouraged because it confuses people about what you're trying to say.)
