Night and the Doctor: Bad Night

When Amy Pond (Karen Gillan) answers the TARDIS telephone in the middle of the night, she learns the Doctor carries on a very active social and adventuring life while his companions sleep. The Doctor (Matt Smith) then enters the TARDIS carrying a goldfish, whom he claims is actually a British Queen. Amy tries to piece together how the fate of the Commonwealth could possibly be affected by the Doctor, an unseen River Song, an unnamed Prince of Wales and the goldfish. She wants to have a serious conversation with the Doctor about her uneasy sleep, but the Doctor calls for her husband Rory (Arthur Darvill) to come deal with her emotions when he realises that he picked up the wrong goldfish.
