It's Sonic Saturday which means it's about to get all wibbly-wobbly and timey-wimey up in here and we think that's fantastic. So grab your fez, your sonic sunglasses and "allons-y"  Ethan and Ian are here to bring you "Who Do You Think You Are"; a retrospective look at Doctor Who's best moments in preparation for Jodie Whittaker's departure and inevitable successor in Autumn 2022. This week Ethan and Ian are about to change time as they cover the second special of 2009 “The Waters of Mars” as they discuss: the villain that is water, one of the Doctor's single-episode companions and the culmination of the Time Lord Victorious.
