I know everyone else is freaking out for the obvious reasons right now, but I want to talk about Bruno, no, no, no Secret History still being a bop after all this time. (Also, it feeds my Leras theory...)
Oh yeah, Secret History slaps. All around solid story, adds depth to a pre-existing story, whilst fleshing out new characters? That's the mark of a good side story- it is pretty much unnecessary to read it to enjoy MB Era 1, but if you do want to read it, it adds so much.
