Thank You, Doctor Who, For Remembering The Major Season 1 Event Everyone Always Ignores

Warning: Spoilers ahead for Doctor Who season 15, episode 4, "Lucky Day."Doctor Who season 15, episode 4, "Lucky Day," includes a subtle but unmistakable nod to a huge event from Christopher Eccleston's era as the Ninth Doctor, which is a huge relief after years of the show ignoring the event in question ever even happened. With Eccleston helping kickstart Doctor Who's modern era, the Ninth Doctor's long season quickly became instrumental in bringing the long-running British sci-fi to new audiences in 2005. It did so by combining small-scale storylines with huge extraterrestrial arcs, which makes "Lucky Day" the perfect episode to acknowledge one Ninth Doctor episode in particular.
