Though he displays many simple expressions on his mask, from dots as eyes to show where he's looking, to the classic 'frisk face' of -_- when unamused. Question marks or Exclamations to make up for his monotone's lack of clarity. Or anything else. This is the expression Ashton tends to bear when purely in the company of those he trusts, who know he is not truly a masked human, but instead a Synthetic. A tired soul to his core, but one who's made it to a much better place in life overall with the help of the few he does trust. The one concept he still could use a little help conceptualizing, being that any person, even artificial, can use some more support and care.
