Kenric was a challenge to fancast and even now I'm not very happy with the fancast but I still think it's good.

The face (mainly the smile like his smile) just embodied Kenric:

Eddie Redmayne (even his last name is perfect)
Or Stefano Masciolini who's name is impossible to type.

Sidenote: I feel like every kotlc fan is a Harry Potter fan and a Riordanverse fan, and a lot of them are mlb fans.
