(You can do a time skip to after class, if you want.)
"Twelve more minutes, class." Light said lightly, engrossed in writing in the Death Note, not even having to look up at the clock to see what time it was. He had 65 more names to write. [i]I have to keep a close eye on the diary holders, and make sure they don't kill Minene themselves otherwise I can't get her diary. Especially Minene, after class I should check to see if she planted any bombs around the school. Though, I haven't seen her diary yet. Well, obviously she had to have brought it with her otherwise she probably wouldn't get out alive, which she won't.[/i] Light thought to himself, continuing to write names.
