Does the glass/perspex separating teammates have some special property that allows sound to pass through or are you all wired up so you can communicate quietly with each other without the other team hearing?
Possibly a question that was asked and answered in the first episode of this series.
Nope and nope, at least in the first 3 episodes I've seen (not seen last week's or tonight's yet). Indeed, contestants were having visible difficulty in conferring, with more than one "Sorry, what did you say? Can't hear you!" type moment occurring.
It does seem unfair, as it means that the other team have an even better chance of overhearing deliberations than they already had, but I suppose that works both ways round.
Of course,
Pie Pie Eater may be able to shed some light if I'm mistaken.
