Attack on Titan discussion (NO SPOILERS)

[CosmicK3rbal]

NO SPOILERS FROM THE MANGA SPOILERS FROM THE ANIME ARE ALLOWED

Anyone here watch this awesome anime? If so, feel free to chat about it here, just no spoilers from the Manga (I don't read the manga) and keep it friendly. I will start with a question, anyone have any ideas on who is in the female titan? Or the other "Titan Shifters" ?

Oh come on, I cant be the only fan of AoT here!

You're not

Though it'd be hard to discuss the show without some spoilers, especially since spoiler tags are still missing

I haven't read the manga so I'm in the dark about a few things, such as why titans are hot when they don't have skin, why the intelligent ones don't have skin, why they're so light (I think squad leader Hanji said they may be made out of air?), and whether Shingeki no Kyojin is set in the same universe as our own? Is it possible to discuss/explain these without spoilers?

Well I meant no spoilers from the manga. Anything else is okay. Btw, I remember hearing that the universe it is in is the same, but 2000 years in the future.
