Most probably. My sister and I had a chocolate cake for Mello's birthday, and we were planning to celebrate Matt and Near's as well, but since we don't know BB's birthday we might as well celebrate/mourn his death.

BB is not dead.
Don't do that to me.

That's right! He's not. He hiding ... with L in the closet. ^^ He's going to have a 2nd coming to the WORLD.
