:: For those who want to know, when it comes to psychokinetics, John is a lot stronger than his female counterpart. John still has anger issues as he was isolated in the past, however the isolation didn't break him, it made him stronger. He also has trust issues since he was a test subject at Hawkins lab and it takes a lot for him to trust you, since trust doesn't come easy for John.
At first, he comes out cold, but as you get to know him more, he begins to warm up to you and show the real him. He does have a tendency to manipulate his enemies. John is shown to be incredibly empathetic, sweet, and curious about the world. Unlike his counterpart, he never was easily distraught, now, most people would run away from danger, not him! He like to run right into it.
