That's what I'm guessing. We know he was a young child in the first series (no confirmed age, but I estimate about 15 or 16). Ten years later would make him about 25 or 26. I'd definitely put him in his mid thirties now. Not old enough to have gray hairs yet, so not 40. But he's definitely a real man now. It's pretty exciting.
