In the webcomic, Saitama tried to jump into combat the moment he arrived, the only reason he didn't get to fight was that Flashy himself kept Saitama from getting involved, Garou ignored Saitama and other S-Class asked him not to jump in.
And even then he was mostly confused as to what the hell was going on.
In the manga he just lets Flashy go fight alone for some reason despite knowing him significantly more in the manga.
He just decides to ignore the clash happening around him for literally no reason so Flashy can get beat up like the other S-Class.
It makes Saitama look pretty dickish all things considered, and not in a funny way like the WC, but in a more incompetent uncaring way.
