Birth
When the Seventeenth Doctor regenerated within the safety of the TARDIS, this Doctor was left to pilot a crashing TARDIS down towards the Earth. The Doctor suffered a terrible accident causing him to have amnesia, and intern, he believes he is an ordinary human on planet Earth. During the days of 2018, this version of the Doctor lives out his life until the age of Thirty, under the guise known as Oscar Parks. From here, he meets an earlier version of his Seventeenth Incarnation across the series, and intern, become this Doctor's companion. The Doctor knows that there is something wrong with Oscar Parks as he seems to have a highly knowledgeable mind when it comes to the time circuits of the TARDIS. At first the Seventeenth Doctor believes Oscar to be another version of the Master, but after close inspection (Near to the end of the Seventeenth Doctor's life span) he discovers that he is a future version of himself:

"17: Oh, wait, i know who he is. I know who you are Oscar! I know why i met you. To remind me; my future is in safe hands"

After this moment, the Seventeenth Doctor proceeds to regenerate into his 18th form and intern his amnesia begins. After the Seventeenth Doctor leaves in the TARDIS, preparing to regenerate, Oscar is witness to it all. After an encounter with the 31st Master in his first Episode, his mind is cracked. With the Master hoping that revealing the Doctor's true self would be too much for this incarnation of the Doctor to handle, and intern, drive him mad, the Master mind-melded with this incarnation, snapping him out of his amnesia. This version of the Doctor was then able to save the day, and intern, began looking for his TARDIS again. On the way, he was able to find himself some new clothes. He was lucky that Oscar had a life as an unsuccessful stage actor, and intern, was able to use costume and props to build up an ensemble for his own outfit.
