Peeta is definitely a strong character so many underestimate him. Peeta is brave and tough yet not afraid to be vulnerable
Josh is good at expressing his emotions with his eyes a lot of actors can, but not every one. Jensen Ackles is amazing at it and I can tell Josh is as well. There are so many scenes I can give examples of I'm going to go with his scenes in Mockingjay. Yes he didn't have many scenes but the few he had he stole the show. That scene where he told Katniss to run you could see it in his eyes the desperation to break free of the control the need to protect Katniss I was blown away.
