ITS OKAY ANON. I CAN EXPLAIN.
((Disclaimer: This is not the only way to interpret Misha’s tweet. But it would makes sense if SPN was outing Dean as Bi soon and Misha knew about it, here’s why…))
You know how on tumblr there are those pictures that people reblog and even though there is something obviously disturbing and wrong with the picture, people reblog it and ignore the obvious, instead adding comments like, "wow what a nice poster on the wall -I love that band"
And then someone else reblogs it and says, “What is wrong with you people? Is no one going to talk about the fact that…” and at this point you’d expect that person to state the obvious-wrong thing in the picture but instead they pick out something that isn’t even that terrible- in fact its a silly thing to notice, especially compared to how wrong the obvious-wrong thing is.
And that makes it funny.
NOW, Misha’s tweet can be interpreted the same way.
Lets say Supernatural IS developing Dean’s bisexuality (not necessarily pertaining to Destiel) and Misha knows about it having seen scripts we have not seen. This episode would have been the first blatant suggestion.
"Good for Supernatural being brave enough to…" this is the point where you expect Misha to comment on the on the obvious- (just like in the tumblr meme) but instead he says “denouncing Nazis”
The fact that denouncing Nazis is not even that ‘brave a stance’ in the first place, especially compared to revealing dean as Bi which would be a brave move for SPN….
Thats what makes it funny.
It didn’t make bisexual Dean CANON but it was certainly a big step towards it. Let me try to explain why people think so…
Character development: While you might act like that, you’re not DEAN. In the past, when Dean has been hit on by men who he wasn’t interested in. He has simply smirked and said he doesn’t “swing that way”. But this time he acted extremely flustered and very much like a teenager with a crush. He even tripped over the table!
Phrasing: WE HAD A MOMENT / MY GAY THING:
Aaron said he thought they had a moment. not just indicating his own interest in Dean but that he thought Dean was into him as well. He claimed he thought he was picking up gay-vibes and interest on Dean’s part.
Dean calls it “MY gay thing” his wording is subconsciously implying that Dean also thought it was mutual.
You coulda fooled Dean:
"You mean we didn’t have a moment?" Again, Dean says "we" which implies something coming from Dean’s end as well.
And when it all turned to be a fake from the other guy…
Dean says “you really had me there…” it’s almost a little hurt sounding, because the main reason Dean bought it? There was some interest on Dean’s part that he was unable to deny…
Again, all this is implied and not yet canon… but it’s as close to canon as bi!Dean has ever been, and it’s very encouraging in terms of future exploration of Dean’s sexuality.
