[On the dance floor, Brian and Justin get down. Brian picks up Justin's shirt off the ground and hands it tohim.]
Brian: Your loosing your shirt.
Justin: You almost lost yours.
Brian: Yeah, I still have no idea why he dropped the sue.
Justin: It's a mystery.
Brian: I guess I'll have to be more careful who I fuck. --这里只是说以后要小心kip这样子的人吧。
Justin: Lucky for you, I turn eighteen tomorrow.
Brian: What do you want for your birthday?
仔细看了这段,觉得其实也没有明确说B知道了。不过意外发现最后一句,B竟然会问J生日要什么,第二季里不是说不过传统的生日的嘛。
