Tread Perilously's Doctor Who month continues with "Arc of Infinity."

When an antimatter creature attempts to merge with The Doctor, his TARDIS is recalled to Gallifrey. The High Council of Time Lords intends to terminate The Doctor to prevent the creature from succeeding in its plan, but it might just be a ruse perpetrated by a Time Lord in league with the anti-matter entity. Meanwhile, Tegan flies to Amsterdam to hang out with her cousin, Colin. But will his plan to sleep in a pumping station lead her to a reunion with The Doctor? Oh, and why does the commander of the Gallifreyan guard seem so familiar?

Drew Siragusa from Fanbase Press joins Erik and Justin to discuss the story and his hypothesis about its connection to a New Series favorite monster. Justin invents a new role for Tegan thanks to her costume change. Erik explains the existence of writer Johnny Byrne. His reasoning for watching "Arc of Infinity" is also revealed. Drew and Justin debate whether or not Tegan's cousin is meant to be Australian. Everyone tries to figure out why the cousin was in Amsterdam to begin with. Justin speaks out against whale clubbing and, as it turns out, The Doctor always worked for Division.
