Also want to say how much this idea has the power to remove the stigma associated with seeking therapy or similar help.
In truth probably every person in the world should be in therapy and would benefit mightily by seeing the right therapist. So I'm not thinking of characters with known mental/emotional health issues like Jessica Cruz's well documented anxiety.
I'm looking forward most of all to seeing Sanctuary used for characters you'd never imagine might benefit from therapy.
So I'll start with Clark Kent/Superman. Because having a well-adjusted hero avail themselves of the benefits of therapy would be what I'd most like to see.
In this day and age there shouldn't be ANY stigma associated with mental health issues or therapy but we're not at all there yet. Seeing someone like Superman seeking help could help with the stigma of seeking mental health care at all. So many people die each and every year owing exclusively to that stigma and the resultant resistance to seeking this sort of help. No one is so "sane" or well-adjusted that they wouldn't benefit from talking to a wise, trained listener about all the things one can't say to a person they know without fear of judgment or reprisal. That's the power of therapy to me and, again, I think 100% of people would benefit from being able to speak openly about such things without fear of judgment.
I don't care to see Arkham inmates in Sanctuary as it only underlines the existing stigma. I'm looking to see the most well-adjusted characters opening up in a way that tells us that it's strong, not weak, to seek such assistance.
