[Voice] Waking Up from the Experiment

[A very groggy Hiro wakes up with absolutely no memory of what had happened over the past several days. He has no idea that he spent the past several days as an alternate universe version of himself, though he did find one clue that something strange happened...]

Ugh... hey, everybody. It's Hiro. Something weird must have happened during the experiment we all went through, because I went to sleep on one day, and now I'm waking up several days later. Does anyone know what I did over the past few days? I don't remember anything...

Well, I did find something. Somehow, some woman got her hands on my journal, and she recorded a voice entry asking about Yamato, who's someone from my world. Can anyone explain that?
