dave reached the bottom of the staircase first, and he called out
"barabara? where are you?! this isnt funny any more!! we want to
go home!" you and dave are now in complete dense darkness. you
cannot see dave anywhere, you can only hear him; you say that barabara
isnt here and that you should just go before you get lost. dave
agrees, but when you both turn around, you both gasp in horror to see
that the sdtaircase is missing!!!
