1: pretty much anything jack can do, up to the highest possible point.
Like, in the episode jack, the woolies and the crichelites, jack picks a lock with his hairpin, that,s pretty hardcore, i don't expect my jack to do that. But i expect him to perform well in the maximum situations possible for jack in the series, witch is the challenge here. Jack is a monumental project.
2: i want it to BE samurai jack, to the highest point.
3: Ideally no rebuilding, jack doesnt rebuild, he learns.
