I am starting to think the same as you. I mean, that eren has an older Sister, and that girl knows the same as Eren's father Grisha. She maybe is a shifter one, knows the secrets about the titans, and also a new ability that is shown: manipulate mind. For me, there is no other logical explanation for this lady. I though and i wanted to believe that i was Eren's mother. But that girl looks younger. (just a little bit). For now, it is the theory that has more sense... it can't be Eren himself. If it is... trying to explain the reasons go beyond reasoning.. you would have to agreed with that fool Time travel theory. So... ill go with that too xD there is a twin sister :3.
