You said it yourself. The metahuman is not a Pawn but a mundane Actor.
It all stems from inheritance. Actor is the base class, the deeper we go, the more specialised classes become:

- a Pawn is a Pawn (obv!) and an Actor
- an Actor is just an Actor - it does not know things Pawns or Characters can do
