When actor Varada Sethu was announced to be playing the new companion in the upcoming Doctor Who season 2, some fans were initially confused. That's because Sethu has been in Doctor Who before and not only that, but very recently too.
As you may recall, in the last season's brilliant episode 'Boom' Sethu played a character named Mundy Flynn, a marine fighting in a war on the planet Kastarion 3. However, in the upcoming season she will be portraying a totally different character named Belinda Chandra, a nurse the Doctor meets taking her on adventures through time and space.
