The brother probably doesn't want to pry in their life. And the other one -should be happy they didn't do anything yet- he suspiciously knew from the start that they slept in different chambers (until that scene they suddenly slept in same room LOL).
But anyway even if they did brought it up won't it be awkward telling: "So you've done it congrats" (≧∀≦)
