no I don't think he raped him, I think walker only did it to try and get into his heart as he realised that was the only way to get to him. Walkers not gay though really (i dont think) so it must have been an ordeal for him. It is difficult to say, because Brendan broke so many of his own rules and beliefs, for example, it was said Brendan would never harm a woman, yet he killed Nana Flo
Brendan's dad sexually abused him. Nana Flo asked him if it was the abuse that made him gay,Brendan said no. However I'm not sure if he was beaten, but he told Ste a year or two ago his Dad beat him, but never told him anymore than this
