With "The Waters of Mars" and the two-part "The End of Time," two eras come to a close on Doctor Who and Bigger on the Inside. Today, Dan and Mike bid farewell to Russell T. Davies and David Tennant, whose impact on both shows must be praised. Please visit www.patreon.com/biggerontheinside.

In Bigger on the Inside's penultimate David Tennant episode, Dan and Mike speak about Dreamland. The computer-animated adventure is lackluster, to say the least. More than that, though, the guys read lots of e-mails and discuss Patreon.com. To visit the Bigger on the Inside Patreon page, or to gather more details, head to www.patreon.com/biggerontheinside.

Mike has a new career in mind, and he needs your help to make it happen. Please listen for details, then follow this link if you wish to contribute: http://www.earth-2.net/donations.php.

The Doctor must unravel the mystery of a man claiming to be The Doctor, all while stopping the Cybermen from destroying London in 1851 ("The Next Doctor"). Then, a pleasant bus ride turns into a nightmare when a hole in space threatens the Earth ("Planet of the Dead"). Dan and Mike also discuss two Doctor Who shorts: "Music of the Spheres" and a segment from Tonight's the Night. The guys read through lots of e-mails, bemoan poor special effects and costumes, and sort of disagree about one of the stories. Also, Mike makes a call for donations.

An apocalyptic pocket universe is created around Donna, in which The Doctor dies and Rose Tyler carries a message for him ("Turn Left"). Then, ending the fourth modern season, Davros and The Daleks return to end everything ("The Stolen Earth" / "Journey's End"). From there, Dan and Mike take a look back at Catherine Tate's tenure on Doctor Who, and rank the final full season overseen by Russell T. Davies.

A peaceful trip to The Library finds unimaginable creatures in the shadows ("Silence in the Library" / "Forest of the Dead"). And while on holiday, The Doctor must battle his own words ("Midnight"). Also, Mike has a theory about Clara, a listener war begins (maybe), and River Song debuts!

After being thrust into a war, The Doctor becomes a family man ("The Doctor's Daughter"). Then, he and Donna help Agatha Christie solve a murder mystery ("The Unicorn and the Wasp"). The guys decide that Henry Gordon Jago could be Colonel Curbishly, and Dan is proud of his new status.

The Ood stage a revolt against their slavers ("Planet of the Ood"), the Sontarans wage war for Earth ("The Sontaran Stratagem" / "The Poison Sky"), UNIT returns, The Doctor makes a political statement, Ian Chesterton flies a jetpack, and Mike's opens a tumblr. Also, there are spoilers for the second half of the seventh season between 7:23 and 12:47.

Donna Noble officially joins The Doctor as they aim to stop aliens from turning Earth into a breeding planet ("Partners in Crime"), and then they must make the ultimate decision: Pompeii or the future of humankind ("The Fires of Pompeii").

Forget all of the talk about the weather, the very first modern multi-Doctor story ("Time Crash"), and Kylie Minogue's turn on the program ("Voyage of the Damned"). What makes this episode of Bigger on the Inside so historic is that Dan and Mike mark the very first appearance of the man, the myth, the legend: Wilfred Mott!
