@ I don't remember where I read this, but some dude said the EreMika moments in the anime (like the one you mentioned) were there just because someone in the production team thought it was great. LOL. Of course this person, either hated the anime or couldn't remember that this happened in the manga too, and more times than in the anime itself. So, "Mikasa has feelings for Eren?!". I'd say "definitely".
