[SPOILER] On Buck and Eddie's conversation in 7x5...

Specifically, on Eddie expressing surprise that TOMMY was gay, and not Buck...

I'm cheering for a Buddie conclusion myself, and I wondered what this means for the two of the them. While it seems like a great thing for queer acceptance (for Eddie to have assumed Buck was bi or gay and still be as emotionally comfortable with him all this time), but it also seems like a strike against Buddie happening. That would means Eddie has been aware of this for a while now but hasn't acted on that information. Or maybe Eddie was just very good at hiding his own surprise?

I have not watched the series prior to the last 2 episodes (we all know why lol, I've only watched some scenes and compilations on YouTube), so I don't know these characters as well as nearly all of you.

What do you make of this?
