Intelligent, resistant, moral, he’s made to do things. He's made to perform the more complicated parts of their exploits. Shem, the put-upon. He’s always drawn back to the family. Never walks away. He likes walks. Longs for a lover. Has one. He's leaving her, plans have been made. Can’t escape sense of obligation. Wants inner strength to be purely emotional. Imagines it will free him.
He falls in love easily, with everything. It’s hard for him to leave things. Hard to leave even particular places on the street. Hard to walk on.
