At least this one is different! And is kinda cute, well I think it is personnally. If you saw the spoiler's 2 minutes scene, the way Gretchen's revelation of her feelings contrasted with Claire's accusation of betrayal was nice! And then the kiss, very cute! And then Claire's face: Priceless!
I checked around the web, the views for this spoilers are so damn mixed, it's unbelievable! Some love it, some hate it! As you probably well know by now, I'm in the first category! But I totally get that some people don't get it! This is a bold move indeed, and not everyone likes that!
One thing however, I want to speak out. Hating this upcoming scene, ok. But this maked-up argument that's it's a rating ploy and all: This is getting annoying! 1- It has been proven wrong and 2- Even if it were true, it doesn't have an influence in the quality of the scene itself! It'd be like being again world peace because some people might gain something out of it, things not as honorable (ok, this is an extreme exemple, it's just to illustrate the ''hidden agenda'' logical fallacy).
You can say you don't like it because it doesn't feel like Heroes. Or that it is OOC for Claire (I don't think it is (Claire-Elle), but you might). Or that it wasn't handled well. Or you can just hate it, without stating why: There is no need to speak out reasons to like or dislike a subjective opinion of quality. But if you state arguments, make sure they make senses please, not those kind of logical fallacies. 'cause, well, by nature, they don't make any sense!
EDIT: To bwm27: I kinda hope you're wrong and Riddler's right, on this one. To me, the Claitchen kiss only worth something if it leads to something. If it's just a kiss, then Claire's ''sorry, I don't like you that way'' and Gretchen's kinda sad but ''ok, let's be friend then'', well then I'll have to join side with all those who disliked the Claitchen idea! Which is kinda rare, I'm rarely on the ''haters'' side!

But I will, if they just scrap out the lesbian relationship just after a kiss!
So, yeah, I won't judge the Claitchen only on the kiss, but also on what is coming afterward! For now, I think it's a nice move for the show and, like I said earlier, Gretchen's love declaration is kinda sweet! So I'm positive! But it has to lead somewhere to stay that way!
