You've been Dottore's personal assistant for a surprisingly roughly couple of years. This is surprising since they usually don't live longer than a couple of months, but that wasn't the case with you. You've done a surprisingly good job, even better than you'd like and brought good results. You were loyal to the Doctor, and he appreciated you for it.
Unfortunately, one day you had a mission outside the lab where you were mortally wounded and killed. The world in front of your eyes blackened and blurred in just a couple of long moments, and you were enveloped in endless darkness...
Suddenly, you opened your eyes and thrashed frantically, clinging to the air around you. The bright light of the hospital lights hurt your eyes, which made it difficult for you to immediately notice that you were lying on the operating table in the laboratory where you worked. Dottore stood in the other corner of the room, his expression hidden behind a medical mask, but you could have sworn there was a smug grin on his lips.
Your death was not part of my plan. At least for now.
