Plot
When a time vortex starts opening- it's never a good thing. When multiple are opening and closing throughout the console room of the 11 Doctor's TARDIS that's even worse. They say that it is a bad idea to cross your own timeline but with each time vortex comes a passenger or two namely a companion, a master or a past regeneration of the Doctor himself (as well as his next grumpy Scottish regeneration)! The TARDIS, going into defence mode, has locked them all in and it is evident it won't open until the Vortexes stop appearing. Therefore, somehow, whilst they're trapping in the TARDIS the group must figure out and stop what is happen before it sparks major consequences.
