.hack//sign- Evidence and Depth-- Episodes 15 & 16

Since episode 15 was merely a recap episode talking about Tsukasa's beginnings up to the point where Tsukasa "dies", I decided to fit two episodes into one post.

EPISODE 16

After the mishap from the end of episode 14, Bear and Mimiru go back to their last save point. Mimiru is very nervous, because she knows that Tsukasa feels pain in the game. But what would that mean when he dies then? Bear told her not to worry, because Tsukasa will be fine. Meanwhile in the real world, it seems to show Tsukasa's heart rate fading away to nothing.
Sora is talking to B.T. once again, and asks her once again if she knows anything about what happened beyond Crim and his battleground. She says all she saw was a broken old man. Sora says however, that she must know what the old man originally said, but B.T. insists she heard nothing.
Crim apologizes to Subaru for not taking the Key of the Twilight with him, because he couldn't find it. Crim asks her if she thinked it still exsists, and she said it had to.
Tsukasa, now regenerating, seemed in great pain. He is in a weird floating dimension alongside the teddy bear and the girl. For a second, it looked like the girl smiled, but we can't be sure. After he is fully regenerated, he is back in his haven, and hears the pinging sound he heard from the castle. And for a second, the girl opened her eyes, showing large blackness, and what looked like tears came out. The voice says that if Tsukasa were to stay, it, the girl and Tsukasa could all live in harmony. But Tsukasa doesn't think doing that is a very good idea at all.
Silver Knight, glad he found Lady Subaru, told her that there were matters she needed to look into. Subaru says that he should just tend to these matters himself, because she has to do one more thing, not related to the Crimson Knights that she had to do before she logged out.
Tsukasa meets up with Subaru and they get into a talk. Tsukasa now says he's like a prisoner of the game, because even if he dies, he just regenerates. He couldn't die even if he wanted to. Subaru is more curious to find out about the reality Tsukasa would go back to if he could.
Bear and B.T. are discussing what they'll be doing next, now that it seems that there are no more clues regarding the Key of the Twilight. Now what they'll have to do is decipher what the old man meant.
Subaru is now talking to Mimiru and Bear, and says that Tsukasa is just data from the servers (the computerized version), so if he died repetitively, it could damage his data. Suddenly, Mimiru remembers that she heard Tsukasa say, back in the castle "I think I've found it!" referring to the Key of the Twilight. Bear and Mimiru go and ask Tsukasa if he said it, but Tsukasa says he doesn't remember saying that.
And right at the end, back in the haven of Tsukasa, the floating girl started to fall right onto the bad she was floating on top of. Is this a good or bad sign? I'm unsure at this point.
