This has started bugging me. I know during season two the producers brought in Michael Fjordbak to portray Peter Hale's teenage self. This is okay. During Season 3/4 they brought Michael back to portray Peter again when visiting Derek's past. Here is where it gets confusing, in season 4 Kate turned Derek into his teenage self (still waiting on how that was possible) which means that Derek met Kate probably at least a year after killing Paige, which would mean the fire happened around that same time. With this in mind, each time we've seen Peter at the time of the fire he is played by Ian Bohen (Old Peter). My question is that why the producers would use the "young" Peter Hale actor for the past scenes if those scenes took place shortly before the fire when they used the "old" Peter Hale actor?
