And Talia wants him to join the League of Assassins.
There's a Batman quote about why he avoids Bekka. Being in Bekka's presence makes him feel like his avoidance of romance is creepy and unnatural. "Sometimes I wonder if I'm even human anymore. Sex, love... even the slightest yearning I've repressed and rechanneled into the Almighty Will. How perverse it feels in her(Bekka) presence. Every relationship was a charade, or some reluctant excursion I knew I would never complete."
