Now don't be too hard on Bruce! In all his previous experiences he's been very badly hurt, and he's thinking of Kal's reputation too, as there are certainly rumors going around of what Lex could have done to him. He's just very... damaged. And doesn't believe that anyone could ever love him. *pets him*

There will be more about Bruce's past in the next arcs, arc 3 especially. :)
