Ken & Mike are about halfway through the televised adventures of River Song in Doctor Who now, but they're also back to the beginning (timey-wimey!) as they cover two episodes that uncover River's origins, "A Good Man Goes to War" and "Let's Kill Hitler". There's a lot of things for them to talk about - and to sort out as well, since both stories are crammed full of ideas. Possibly too many ideas. Possibly way too many ideas.
