Hmmm, I think I would be disappointed if Wil was ftm as well. It wouldn't have as much power, especially so soon after Oswald's "reveal." I rather think that it's referring to Wil hiding his true self while he is with the Knights. Also, TheYoungDoyler is a great writer and I think she would be much sneaker than to reveal Wil to be ftm so soon after Oswald's big secret is found out.
