Back in March, clinical psychologist (and awesome comic book geek) Dr. Andrea Letamendi wrote a really great article about Rick Grime’s mental state. Are his hallucinations realistic? Could he really “snap” out of it after seeing Morgan? How bad off is Morgan, anyway? Dr. Letamendi addresses all these things, as well going into more details regarding hallucinations and mental illness. It’s a super interesting read, and really accessible.
