I was afraid that this would happen...just not this fast. I haven't checked forward, but I did wonder if eventually she'd start to lose her memories of her past life. I assumed that she'd slowly start losing memories of her family piece by piece until eventually Takae just disappears and all that remains is Marika with a blank spot in her memory of the time Takae was around. Now I think it will be a series of Takae and Marika slowly swapping places. Marika will start appearing more frequently, and Takae less, until eventually she'll just stop surfacing at all...
