"Rebirth"
While dealing with the aftermath of the explosion of Anti-Time, the TARDIS created a series of holographic projections, taken partly from reality and partly from the memories of the Doctor, Charley Pollard and the TARDIS itself. One projection it created was the event at Winkle's Wonderland, for information on the Divergence. Inside this projection it placed Charley in the role of General Mouse and itself in the role of Corporal Dodo.

Soon after, the TARDIS was drawn into a special corner of the Matrix and reduced to scrap by Rassilon and Zagreus. Before being destroyed, though, it recreated projections of Walton Winkle, Reverend Matthew Townsend and Lord Provost Tepesh in the Matrix to help return fragments of the Doctor's mind to him. The projection of Winkle could repair K9 Mark II, something only The Doctor and Romana could do. However, he was killed with a dagger forged from the essence of the TARDIS. (BFA: Zagreus)
