Bruce (a.k.a Patient 176) was having one of his typical days in the psych ward of St. Mungo's - he was talking to the walls & making voodoo dolls (that looked more like deranged bunnies. And he didn't call them voodoo dolls, he called them "bruce babies". ahem) out of bits of cloth. Given his status as a long-term resident of the psych ward, he really had no clue the riot was taking place at the Ministry. He heard a couple of nurses mumbling about riots and government, but he wasn't aware that a coup was taking place right about the time he started lecturing the walls on the history of the British royal family (using his "bruce baby" dolls to illustrate, & turning his bed, a chair & his sheets into the Royal Palace).
