Can your character see through Gil's Mask? Yes; Mono is Deeply Strange in what his entire being is. Plus his home realm with the Pale City and the Transmission Tower (as well as the cycle he's locked in) carries a Lot of parallels to CtL fey realms, and we discussed this. /fingerguns
Would you be alright with Gil using Witches' Intuition on your character? Yes!!! 100% yes.
Anything else? While he's scared of a lot of things very much all the time, Mono's also gotten really used to having to face them on the regular; the fear no longer stops him from moving forward. He's got an opt-out here just in case, and permissions here.
cw: guns, murder, violence against children, medical badness, mannequins, body horror... the works

What is your character scared of? So much. Everything. Adults. Being trapped. Being hunted. Being carved up. Being vulnerable. Hospitals. Doctors. Adults. Teachers and bullies and schoolhouses and things moving in the dark and disembodied body parts. Uh, guns and too-open too-bright spaces and traps. Adults. And especially being alone.
