I have a question about the last Heroes episode (1961).. I'm a little confuzed on who the four kids were..?

Okay so me and my mom think that, of course the girl was Angela, but we think that the kid who was black was the guy who can now erase people's minds who was in the beginning of the series ( I forgot his name), that the kid with the gles was Noah, Clair's adoptive dad, but we have no idea who tho other kid with the blond hair was.. Bobby? Are we right? Who was the blond haired boy? Thank you for all your answers. (:
