Just a partial list:
*Mohinder calling HRG, well, "Horn-Rimmed Glasses guy."
*Ando telling Hiro, "If you mention cape and tights, I'm out of here!"
*Peter and Simone talking about how everyone's connected, somehow. (Actually, that little bit was mentioned a lot that episode.)
*Mohinder talking about his father: "It's always 'why.' There are never any answers, only questions." (Or something to that effect... How his father would answer with another question, or something like that. Essentially, describing what a serial show like Heroes and Lost is like, hehe.)
Anything else I missed?
