Something about Beckett calls out to me. I don't really know what it is. I just can't seem to read John as even the least bit queer. Not that it wouldn't be a good thing, but... meh. I feel the same way about Jack/Daniel from SG-1, too, which puts me at odds with that entire fandom. I simply do not see it, except when it's knowingly being done to tease the J/D fans.
