well, when i regenerated into my new form, the energy output was too high because this was my 18th regeneration which was exceeding the limit of 12. anywho, my tardis was crashing and i was helplessly trying to stabilize it. My tardis couldn’t handle it and rammed into the earths crust. My tardis was now flightless and needed to upgrade. I tried to use my sonic but all it did was zap me and overheated! In just seconds a new tardis materialized right in front of me, I walked inside of it to see a new design, WITH THE CIRCLE THINGS!!!! god I love the circle things. A new sonic ejected out of the console. Very similar to the one River Song showed me.
