After a week off, Jason and Paul return to Talking Timelords! ...or is it their Zygon doppelgangers?  Either way "The Zygon Invasion" and The Zygon Inversion are discussed at great length.  Prepare yourselves for a lot of fanboying!  These episodes really hit the mark for your hosts as they discuss what could be Peter Capaldi's greatest episode, to date!
