.hack//sign- Entanglement-- Episode #12

As the episode begins, it shows two people, and their speech is in Japanese. Therefore we might not know what they're talking about. It seems to be a fight between the two people.
In the World, Tsukasa gives Mimiru an item that she could use. She didn't want to upgrade it, so she just took it to sell later. When she talks about how she liked to be in the mall and talked about one, Tsukasa seemed like he knew what she was talking about. Mimiru guessed that Tsukasa was from Tokyo, but he wouldn't tell her if she was correct or not. Tsukasa wanted to stay with Mimiru for a little while before he went back to his place.
Subaru is talking with Silver Knight and tells him that no matter what happens, no matter what time of day, she wants e-mail notification of any sightings of Tsukasa.
When Tsukasa returns to his haven, it's a lot darker than it usually is, and there are numerous vines surrounding the floating girl and the weird teddy bear that always seems to be there. Alarmed, Tsukasa tries to pull the vines off the girl, but the vines grow back as soon as they're pushed away. He gets scratches and hurts himself, and then gives up.
Bear says he has an idea back where him and Mimiru are talking and logs off.
Maha looks a little angry and starts to come at Tsukasa like he's going to attack him.
Bear is now talking to B.T. about what he found out about Tsukasa. He found out that Tsukasa has severe respiratory problems, which was caused by temporary insanity.
Tsukasa, horrified, is now listening to the voice. It tells the story of the Little Mermaid, and Tsukasa is confused as to what it meant. The voice doesn't want Tsukasa to go back the the 'Ludicrous World', it just wants Tsukasa to stay.
Crim and B.T are having their usual talk, and they start to think that Tsukasa and the Key of the Twilight are related. Both the Key and Tsukasa surpass the system, so there might be some sort of connection between the two.
After B.T. leaves and Subaru comes, Crim thinks that Subaru should quit the Crimson Knights. She's extremely worried about Tsukasa, and the Knights shouldn't be a huge burden to her.
Bear, talking with B.T., finds out that if Tsukasa does get back to the real world, he might not remain concious. He is in very bad condition at the hospital.
When Mimiru sees a very sad-looking Tsukasa coming toward her, she sees the scratches he has on his body. When she asks how he got them, he doesn't answer. Bear joins them and tells Tsukasa that him and Mimiru want to find the Key of the Twilight. They ask if Tsukasa wants to join them, but Tsukasa gets upset and runs off yet again. He returns to his haven and thinks that he should just stay there. As soon as he says that out loud, the vines wrapped around the weird teddy bear and the girl unwrap and disappear.
