I caught up with Prasanna Puwanarajah, last seen starring opposite Suranne Jones in Doctor Foster about returning to our screens opposite Benedict Cumberbatch in Patrick Melrose.
Prasanna plays Johnny Hall, Patrick’s best friend, confidant and a fellow addict. When Patrick hits rock bottom, it’s Johnny who is there to pick him back up.
As time goes on, Johnny enters recovery alongside Patrick, but his path takes him through the Narcotics Anonymous programme, while Patrick chooses to navigate sobriety in his own way.
Later, Johnny becomes a psychotherapist, and is the first person to learn of the secret that has haunted Patrick since his childhood.
