Reading some of these posts reminds me of my early teenage years and hearing, "Are you sure?" "Maybe it's just a phase," "You're too young to make that decision," (clearly they meant coming out, amirite guys) and "You're just confused." Sexuality is so damn fluid that discussing it always feels like a chore where someone will always feel offended.
As for my take... the feelings are always there--maybe not the knowledge of what you are--but you can tell you're not like everyone else even if you've never been exposed to anything gay-related. Yes, even as a child. 13, 14--or whatever age Ellie and Riley are--it's old enough for the feelings to be real. And when I say "feelings," I don't mean love, but those that let you know your preference, if any. For people to watch the build-up to the kiss scene and then think it's just friends being friends...
This is why LGBT inclusion in games feels like such a double-edged sword to me sometimes. If it's not stated outright for the masses in the material, you eventually have a "are they or aren't they?" war on your hands. A kiss isn't enough; clearly they're just really close friends, or they don't know what they're doing or feeling, which causes people to parrot what every LGBT individual has heard in their life at one time or another--and that's that, somehow, our issues can be swept under the rug by third parties because they know better than us. Ironically, if they were to state it outright in some way (in the material. e.g., "I'm gay, y'all"), then you'd have people claiming it's forced or something because someone's gayness shouldn't be a noteworthy trait. I guarantee it.
It's like the creative team can't have their cake and eat it, too, no matter how they approach it. The same could be said of the represented group.
Anyway, it's ultimately a work of fiction. Until there's irrefutable proof by the devs about Ellie and Riley, I suppose we'll have to keep hearing all sides of something that shouldn't be a debate. Kanji Tatsumi, anyone?

I thought the kiss was cute. The facial animation and motion capture on this DLC was great. The subtle features in Ellie's smile and eyes after she pulls back and kind of awkwardly fumbles... really nice touches. ND does some good work.
