Hidden Face

TAKE THAT MASK OFF 

The title describes this UnTrash perfectly: it's when someone's face is often hidden from view. This can be done for multiple reasons. One is to conceal the identity of the person which has multiple reasons for happening in itself. Another is to keep the mystery of who this person is alive. This can be paired up with this person being the Silent One to keep the mystery even more alive. A third is because the creators just don't want to show this person's face.

A face can be hidden using two main methods: always keeping the person's face off-screen or by having them wear a mask or mask-like piece of clothing. Off-screen faces are reserved mainly for adults (namely parents), while masks are more universally used.
