So, this week has been the week that all the Doctor Who fans have either been locked away in solitude rewatching all their favorite episodes of the infamous BBC series in the back to back marathon leading up to the big 50th anniversary episode, or have been blogging and posting non stop about how much they love Doctor Who, while rewatching said episodes, of course, lol. Anyway, David Tennant and Billie Piper will be returning in the 50th Anniversary episode, as I'm sure everyone knows by now, and I'm super excited! David Tennant is one of my favorite actors and I can't wait to see him back as the 10th doctor! The 50th Anniversary celebrations are kicking off really soon... 1:30pm central time on BBC America.
