sidz

“There are men who seem to be born to be the reverse, the obverse, the wrong sidze. They are Pollux, Patrocles, Nisus, Eudamidas, Ephestion, Pechmeja. They only exist on condition that they are backed up with another man; their name is a sequel, and is only written preceded by the conjunction and; and their existence is not their own; it is the other side of an existence which is not theirs. Grantaire was one of these men. He was the obverse of Enjolras.
