Complicated space-time event
From Jenny Everywhere Wiki
In one universe, when Wednesday Addams entered the TARDIS, the ship detected that she was a complicated space-time event, somehow connected to multiple versions of her in other universes including a child who'd burned down a summer-camp, an adult living in L.A., and a lovelorn musical Wednesday. The Eleventh Doctor speculated that it was because of this status that a Weeping Angel had recently tried to feed on her. (PROSE: Wednesday and the Weeping Angel)
