He can change a doll’s hair but he can’t ask his friends for help when he goes back in time to take on a sociopath that nearly destroyed his entire family.
Actually it looks like he just replaced the doll completely.
While a fun example of his super speed I really can’t fathom how he’d even be able to do this. It’d have take him relative months to do and I don’t even want to think about how the city probably would give it a billion codes violations having being built without permits and the like. But that’s me nitpicking. It’s still fun.
With me, it’s always “How long does it take for construction cement to dry?”
