[Rei escaped the house before Asuka woke up - she feels badly about leaving Tsukasa with her, but she needs her LCL treatment, and she doesn't yet have the energy for another showdown. After her treatment, she retreats to the beach, sitting on one of the dunes with her legs crossed in front of her.
That's what she is, isn't it? Not human, not Angel - Almark-san was wrong when he said that someone like her could just make a place for themselves. And he had others like him, so how could he even know? He may have been alone once, but then there were others. There are no others like her.
There is no place for her.
She looks out at the water, and for the first time, she seriously considers ending her life. Not that she will, but she puts deep thought into it. What would it feel like, to drown? Would it be like all the other times, where everything simply went black until she woke up again? But she wouldn't wake up this time. There are no bodies left for her, no dummy plug system. It's useless to be thinking this way.
She draws her knees up to her chest, shivering deeply. She has allowed Asuka to sink too far into her mind. She must find a way to clear it, to re-align with her purpose. The creator of humanity and the woman who gave everything to protect it, they both live inside her, and they would not want her to die. She still has work to do here.]
[She looks up suddenly and glances around - did she hear someone approaching? - then disappears back into her mind when she doesn't spy anyone there.]
