The Doctors are typing away on the TARDIS console, searching for a solution. They managed to discover that the ships' communication systems were linked together. If the systems were to overload, the Time Lords would be forced to retreat. However, they would need someone who would be able to hack into the systems…
"I'll do it!" Hiroki piped. "I'm doing an IT subject, so I think I might be able to pull it off with help." With the help of the two Doctors, they were able to launch a DDoS attack on the Time Lord ships and set them on route into space, leaving their human servants behind.
The two Doctors prepared to farewell each other. 11 knew that because his timeline wasn't in sync, he wouldn't remember the events that happened once he left. Kai and Yui would probably remember, since they were travelling with 11 in the first place. 11 said goodbye to 12 and Hiroki, then set off in his TARDIS with Kai and Yui.
With the Twelfth Doctor now alone with Hiroki in the TARDIS, they finally decided to open the letter that Natsuki gave them. The Doctor asked Hiroki, "Does anything in the letter make you recall anything?"
"I sort of remember this really huge war that happened before I found myself alone with the Beltmorpher. I don't even know anything else, just that."
The Doctor told him, "To be honest with you, some things in the letter made me recall some things as well. There was a time when I couldn't remember what I did to end the Time War because my timeline wasn't in sync. So whatever happened, some of my past selves were at Koshi Castle, but the latest one there couldn't remember it until he became me." After looking around, he said to Hiroki, "Do you want to come with me and find out about what happened at Koshi Castle? Maybe the things that happened there could have been why you lost your memory."
Hiroki accepted his offer. The Doctor began piloting the TARDIS into a time unknown to them, hoping to solve the mystery of what happened at Koshi Castle…
TO BE CONTINUED
IN MOVIE UPRISING BETA
Author's note: Apologies for the seemingly rushed ending. I had meant to finish this story a couple of months earlier than intended, but various events in life changed that. Before I start writing Movie Uprising Beta, I hope to finish tying up all the loose ends in a couple of other stories.
If you don't know what I'm talking about, this story is one of three preludes that will tie into Movie Uprising Beta. It will feature the Tenth and Eleventh Doctors, with Twelve being a side character. I hope it will be better than this story!
