Mello was extremely pissed off. He hated how Near was sitting on his lazy ass, not doing a single useful thing, and here he was, fighting for his life. Mello already lost his best friend, and he found it extremely difficult to forget about him, for the fact that it could have just as easily been himself. He knew that every other kid at Wammys was practically useless nowm seeing that most of them were still scared of something that no longer existed; Kira.
At the moment, he didn't give a damn about B, but he did know it would be an advantage to himself to have B work along side him, a valuable asset. Looking back, he recalled how he used to mentally keep a list in his head, a list about all the dumb fucks he couldn't stand. There were a bunch of them, so that's probably why Mello discarded the dumb list, seeing that it was much easier to just judge a person by there first impression. First impressions were everything right?
Realizing that trying to forget about Matt would be a waste of his time, he might as well avenge his death. Mello would start with killing near, and then just go with the flow from there. Of course, he knew that he wasn't invincible either, and that he would have to be sneaky about the killings.
