Is Mario Bosh (or Bossi) Triela's real father?
In chapter 3, Triela captures, and later frees, a former mafia leader, Mario Bosh.
He claims to have come to the town to meet his daughter (Triela?), whom he hasn't seen in several years.
He later sends Triela a bear as a Christmas present. (He claims to have sent his daughter a Christmas present every year, and Triela has received a bear for Christmas every year, supposedly from her handler.)
It seems odd that Triela also received exactly what she asked for for Christmas from Mario even though she never had the chance to tell him what she wanted.
Side note: this would actually make it the first year Triela has received a gift from her handler, not the first gift from Mario.
Also, Triela's handler hides around a corner, and doesn't show himself, allowing Triela to release Mario.
Is this an actual thing, or am I overthinking it?
