So, after Mario and Mr. Greenie beat the dark star and Fawful, the dark bros. will come in, so Fawful says to the dark bros. to retrieve her, but then the dark bros BETRAY Fawful, and they only want the shards to themselves. (Insert fight here) then, after Mario and Weege beat THOSE guys, they hold the shards up to put them together, but then dark Mario uses the last of his energy to touch the complete star or whatever the shards form, and there's a flash of light.... they are fully possessed by the shards of reality and turn into the ultimate dark bros. (Insert fight here) Then Mario and Weege beat the dark bros. and I dunno what happens next.
