The second Doctor Who Season 9 trailer is here. What do all these images mean? Who are all these characters? Why is The Doctor playing guitar? I guess we’ll find out when The Doctor and Clara’s adventure unfolds on September 19th.

Here are a few episode names so far:

• E1: The Magician’s Apprentice
• E2: The Witch’s Familiar
• E5: The Girl Who Died
• E6: The Woman Who Lived
