The last poem/riddle was about Caecilius!
The people who guessed correctly are Tempest Wolfe, guest, TercesTardis and Anjion.
The next person I'm doing was chosen by Tempest Wolfe!
After I encountered the Master,
and shared a trip with him to the end of the universe,
I became his partner,
appearing beside him for the press and photos.
Following the Master's appointment as Prime Minister,
I was interviewed by Vivien Rook,
who tried to convince me that Harold Saxon was a false identity,
and that whoever he was,
he was putting me as well as everyone else in danger.
When the Master appeared through a back door,
Vivien tried to cover up what she had stated about him,
but discovered that I was well aware of her knowledge,
as she was killed by a Toclafane.
On the day of the Toclafane invasion,
I was eager for the fulfilment of the Master's true intent.
When the Toclafane appeared,
and killed American President Arthur Coleman Winters,
I was calm throughout the entire duration of the events.
Over the year of the Master's reign,
I became cold towards him due to abuse I received at his hands,
prompting me to join in when the world started to chant the word "Doctor."
When the Master tried to escape,
I witnessed Francine Jones raise a gun in his direction,
and when the Doctor and Jack Harkness managed stopped her,
I took the gun and shot him,
wounding him fatally.
Jack managed to disarm me,
as I stared at him emotionless,
at the man who had broken me.
