the reaction is a bit diffrent which kinda change context, if i remeber correctly. Lit.Serena didn't buy hiro "rumor" excuse at all and ask him to give full prep report about his "rumor" which really add to her having to feel guilty to said that it is by her own work with a "rumor" she gather, cause hiro demand serana keep his part about "rumor" shut.
but maybe i remember wrong and serena going to drag hiro ass later.
EDIT:yeah i remeber wrong, serena going to grill hiro ass later.
