#granted we haven't even met blue in the manga yet

[the-nysh]

i wonder how will saitama's interactions with blast effect how he reacts to blue

In the manga? He'll probably consider Blast that much more of an old man for being old enough to father a teen. :P Considering they actually have interacted a handful of times compared to zilch in the wc, manga Saitama should definitely have grounds for a different perspective going in once he's ever introduced to Blast's son. I'm hoping it'll be amusing!
