I have good news on that front. While it's not determined that this Vallo follows the same magical "rules" as the one we're familiar with, I can confirm that the one I'm familiar with has a unique time signature. Meaning that while time moves forward for ourselves, it is stopped in your home universe. Your nephew won't know you're gone - I realize that's a double-edged sword, but it brings me comfort that I won't miss anything back home.
