Doctor
Other You, Mickey and I ended up in a parallel world where my dad was alive and successful, but I was never born. The Cybermen were there. We fought them and Mickey decided to remain there.
Then there was a situation where the Cybermen and the Daleks were ripping a hole through time, the Cybermen wanting into our world and the Daleks needing to open the Crucible.
In order to fix the hole, you fully opened the vortex and it pulled the Daleks and Cybermen into the void. Dad met up with my mom again and you ensured they went to the parallel world with Mickey. I chose to stay back to help you but I was almost pulled into the void as well. The only thing that kept me was Dad coming back, but it sealed me in the parallel world.
