Intro: The marsh creatures, under cover of fog, are after the outliers. If you were an outlier on Alzarius, where would you hide? Well, you could try the TARDIS, if, against astronomical odds, it happened to be there. As long as the probability exists, no matter how infinitesimal, WTTW, Chicago will cover it.

Outro: There is a terrible, sinister secret underlying next week's adventure, "State of Decay." But I won't tell you what it is. You'll just have to tune in next week and find out for yourself. [source: ChicagoEpguides]
