The odd case of Tyro :
**SPOILER**
"But where are all those Tyros ?"
I realise : if Tyro can be over 100 year old, and for exemple was 50 years old on his first loop, where was he when he aged ?
The must be some long periods (months) where there are more than 50 copies of him of all ages in the station... Thus Tyro would account for 1/6th of the station's population !
He should litteraly be everywhere (I imagine a hidden room filled with tyros) or even be able to take hower the station. Unless he spent a huge part of his timeline in coffin safes, or has been attacked a lot but time-Leeches and the Kronophage.
